-## General Workflow
-
-1. Push to a remote branch
-2. Create an MR, choose related labels (not required)
-3. A `detached` pipeline will be created.
-4. if you push a new commit, a new pipeline will be created automatically.
-
-## What if Expected Jobs ARE NOT Created?
-
-1. check the file patterns
-
-   If you found a job that is not running as expected with some file changes, a git commit to improve the `pattern` will be appreciated.
-
-2. please add MR labels to run additional tests, currently we have to do this only for `target-test` jobs, please use it as few as possible. Our final goal is to remove all the labels and let the file changes decide everything!
-
-## MR labels for additional jobs
-
-### Supported MR Labels
-
-- `build`
-- `build_docs`
-- `component_ut[_esp32/esp32s2/...]`
-- `custom_test[_esp32/esp32s2/...]`
-- `docker`
-- `docs`
-- `example_test[_esp32/esp32s2/...]`
-- `fuzzer_test`
-- `host_test`
-- `integration_test`
-- `iperf_stress_test`
-- `macos`
-- `macos_test`
-- `nvs_coverage`
-- `submodule`
-- `unit_test[_esp32/esp32s2/...]`
-- `weekend_test`
-- `windows`
-
-There are two general labels (not recommended since these two labels will trigger a lot of jobs)
-
-- `target_test`: includes all target for `example_test`, `custom_test`, `component_ut`, `unit_test`, `integration_test`
-- `all_test`: includes all test labels
-
-### How to trigger a `detached` pipeline without pushing new commits?
-
-Go to MR web page -> `Pipelines` tab -> click `Run pipeline` button.
-
-In very rare case, this tab will not show up because no merge_request pipeline is created before. Please use web API then.
-
-```shell
-curl -X POST --header "PRIVATE-TOKEN: [YOUR PERSONAL ACCESS TOKEN]" [GITLAB_SERVER]/api/v4/projects/103/merge_requests/[MERGE_REQUEST_IID]/pipelines
-```
-
-## How to Develop With `rules.yml`?
-
-### General Concepts
-
-- `pattern`: Defined in an array. A GitLab job will be created if the changed files in this MR matched one of the patterns. For example:
-
-    ```yaml
-    .patterns-python-files: &patterns-python-files
-      - "**/*.py"
-    ```
-
-- `label`: Defined in an if clause, similar as the previous bot command. A GitLab job will be created if the pipeline variables contains variables in `BOT_LABEL_xxx` format (DEPRECATED) or included in the MR labels. For example:
-
-    ```yaml
-    .if-label-build_docs: &if-label-build_docs
-      if: '$BOT_LABEL_BUILD_DOCS || $CI_MERGE_REQUEST_LABELS =~ /^(?:[^,\n\r]+,)*build_docs(?:,[^,\n\r]+)*$/i'
-    ```
-
-- `rule`: A combination of various patterns, and labels. It will be used by GitLab YAML `extends` keyword to tell GitLab in what conditions will this job be created. For example:
-
-    ```yaml
-    .rules:build:docs:
-      rules:
-        - <<: *if-protected
-        - <<: *if-label-build_docs
-        - <<: *if-label-docs
-        - <<: *if-dev-push
-          changes: *patterns-docs
-    ```
-
-  An example for GitLab job on how to use extends:
-
-    ```yaml
-    check_docs_lang_sync:
-      extends:
-        - .pre_check_job_template
-        - .rules:build:docs
-      script:
-        - cd docs
-        - ./check_lang_folder_sync.sh
-    ```
-
-### How to Add a New `Job`?
-
-check if there's a suitable `.rules:<rules-you-need>` template
-
-1. if there is, put this in the job `extends`. All done, now you can close this window. (`extends` could be array or string)
-2. if there isn't
-    1. check [How to Add a New `Rules` Template?](#how-to-add-a-new-rules-template), create a suitable one
-    2. follow step 1
-
-### How to Add a New `Rules` Template?
-
-check if this rule is related to `labels`, `patterns`
-
-1. if it is, please refer to [dependencies/README.md](./dependencies/README.md) and add new rules by auto-generating
-2. if it isn't, please continue reading
-
-check if there's a suitable `.if-<if-anchor-you-need>` anchor
-
-1. if there is, create a rule following [`rules` Template Naming Rules](#rules-template-naming-rules).For detail information, please refer to [GitLab Documentation `rules-if`](https://docs.gitlab.com/ee/ci/yaml/README.html#rulesif). Here's an example.
-
-    ```yaml
-    .rules:dev:
-      rules:
-        - <<: *if-trigger
-        - <<: *if-dev-push
-    ```
-
-2. if there isn't
-
-    1. check [How to Add a New `if` Anchor?](#how-to-add-a-new-if-anchor), create a suitable one
-    2. follow step 1
-
-### How to Add a New `if` Anchor?
-
-Create an `if` anchor following [`if` Anchors Naming Rules](#if-anchors-naming-rules). For detailed information about how to write the condition clause, please refer to [GitLab Documentation `only/except (advanced)](https://docs.gitlab.com/ee/ci/yaml/README.html#onlyexcept-advanced). Here's an example.
-
-```yaml
-.if-schedule: &if-schedule:
-  if: '$CI_PIPELINE_SOURCE == "schedule"'
-```
-
-### Naming Rules
-
-#### Common Naming Rules
-
-if a phrase has multi words, use `_` to concatenate them.
-
-> e.g. `regular_test`
-
-if a name has multi phrases, use `-` to concatenate them.
-
-> e.g. `regular_test-example_test`
-
-#### `if` Anchors Naming Rules
-
-- if it's a label: `.if-label-<label_name>`
-- if it's a ref: `.if-ref-<ref_name>`
-- if it's a branch: `.if-branch-<branch_name>`
-- if it's a tag: `.if-tag-<tag_name>`
-- if it's multi-type combination: `.if-ref-<release_name>-branch-<branch_name>`
-
-  **Common Phrases/Abbreviations**
-
-    - `no_label`
-
-      `$BOT_TRIGGER_WITH_LABEL == null`
-
-    - `protected`
-
-      `($CI_COMMIT_REF_NAME == "master" || $CI_COMMIT_BRANCH =~ /^release\/v/ || $CI_COMMIT_TAG =~ /^v\d+\.\d+(\.\d+)?($|-)/)`
-
-    - `target_test`
-
-      a combination of `example_test`, `custom_test`, `unit_test`, `component_ut`, `integration_test` and all targets
-
-#### `rules` Template Naming Rules
-
-- if it's tag related: `.rules:tag:<tag_1>-<tag_2>`
-- if it's label related: `.rules:labels:<label_1>-<label_2>`
-- if it's test related: `.rules:test:<test_type>`
-- if it's build related: `.rules:build:<build_type>`
-- if it's pattern related: `.rules:patterns:<patterns>`
-
-## Reusable Shell Script `tools/ci/utils.sh`
-
-It is used to put all the reusable shell scripts as small functions. If you want to set `before_script: []` for you job, now you can set `extends: .before_script_slim` instead. it will only run `source tools/ci/utils.sh`
-
-If you're developing CI shell scripts, you can use these functions without `source` them. They're already included in all `before_script`
-
-To run these commands in shell script locally, place `source tools/ci/utils.sh` at the very beginning.

-# How the `generate_rules.py` works
-
-## Functionalities
-
-This script can do only two things:
-
-1. Auto-generate some labels/rules we need and update them in `rules.yml`
-2. Generate a dependency tree graph
-
-## Schema
-
-This file only used basic YAML grammar and has nothing to do with the GitLab version YAML file.
-
-It has five custom keywords:
-
-- `matrix`: An array of sub-arrays, used to replicate rules by formatting strings. You can use the format string everywhere, it will be formatted recursively
-- `labels`: An array of `labels`.
-- `patterns`: An array of `patterns`. Patterns that not included
-- `included_in`: An array of other `rule` names. It indicates the `labels` and `patterns` will be included in all specified `rules` as well
-- `deploy`: An array of strings, used to replicate rules by adding postfix `-<item in deploy array>`. It indicates the extra `label` used in `rules`, which will explain later.
-
-## How to use this file to generate `rules.yml`
-
-Let's take a complicated example to help understand the process
-
-```yaml
-"test-{0}-{1}":
-    matrix:
-        - [a, b]
-        - [c, d]
-    labels:
-        - "{0}-{1}"
-    patterns:
-        - "{0}"
-        - pattern-not-exist
-    included_in:
-        - build-{0}
-```
-
-1. expand the mapping dicts defined by `matrix`
-
-   After this step, it will turn into 4 dicts:
-
-   | key      | labels | patterns | included_in |
-   | -------- | ------ | -------- | ----------- |
-   | test-a-c | a-c    | a        | build-a     |
-   | test-a-d | a-d    | a        | build-a     |
-   | test-b-c | b-c    | b        | build-b     |
-   | test-b-d | b-d    | b        | build-b     |
-
-   **Advanced Usage: You can overwrite a mapping by declaring it again later**, For example:
-
-   If we concatenate this part to the previous example,
-
-    ```yaml
-    # ... The same as the previous example
-    
-    test-a-c:
-        labels:
-            - overwrite
-    ```
-
-   `rule` `test-a-c` will be turned into:
-
-   | key      | labels    |
-   | -------- | --------- |
-   | test-a-c | overwrite |
-
-   **Mappings with the keyword `deploy` will also replicate by adding a postfix `-<item in deploy array>` to the mapping key**
-
-2. create rules by `included_in`
-
-   After this step, it will turn into 6 mapping dicts:
-
-   | key      | labels   | patterns |
-   | -------- | -------- | -------- |
-   | test-a-c | a-c      | a        |
-   | test-a-d | a-d      | a        |
-   | test-b-c | b-c      | b        |
-   | test-b-d | b-d      | b        |
-   | build-a  | a-c, a-d | a        |
-   | build-b  | b-c, b-d | b        |
-
-3. replace the auto-generated region in `rules.yml` with `labels`, and `rules`. Each mapping will generate a `rule` and all the required labels. `patterns` are pre-defined in `rules.yml` and could not be generated automatically. If a mapping is using a `pattern` undefined, the `pattern` will be ignored.
-
-    - If a mapping key has postfix `-preview`, no `if-protected-xxx` clause will be added
-    - else if a mapping key has postfix `-production`, an `if-protected-no_label` clause will be added
-    - else, an `if-protected` clause will be added
-
-## Graph
-
-All `label` nodes are in green, `pattern` nodes are in cyan, `rule` nodes are in blue
-
-### Requirements
-
-There are a few extra dependencies while generating the dependency tree graph, please refer to [pygraphviz](https://github.com/pygraphviz/pygraphviz/blob/master/INSTALL.txt) documentation to install both `graphviz` and `pygraphviz`
-
-### CLI usage
-
-`python generate_rules.py --graph OUTPUT_PATH`

-# Core Components
-
-## Overview
-
-This document contains details about what the core components are, what they contain, and how they are organized.
-
-## Organization
-
-The core components are organized into two groups.
-
-The first group (referred to as `G0` from now on) contains `hal`, `xtensa` and `riscv` (referred to as `arch` components from now on), `esp_rom`, `esp_common`, and `soc`. This
-group contain information about and low-level access to underlying hardware; or in the case of `esp_common`, hardware-agnostic code and utilities.
-These components can depend on each other, but as much as possible have no dependencies outside the group. The reason for this is that, due to the
-nature of what these components contain, the likelihood is high that a lot of other components will require these. Ideally, then, the dependency
-relationship only goes one way. This makes it easier for these components, as a group, to be usable in another project. One can conceivably implement
-a competing SDK to ESP-IDF on top of these components.
-
-The second group (referred to as `G1` from now on) sits at a higher level than the first group. This group contains the components `esp_hw_support`, `esp_system`, `newlib`, `spi_flash`,
-`freertos`, `log`, and `heap`. Like the first group, circular dependencies within the group are allowed; and being at a higher level, dependency on the first group
-is allowed. These components represent software mechanisms essential to building other components.
-
-## Descriptions
-
-The following is a short description of the components mentioned above.
-
-### `G0` Components
-
-#### `hal`
-
-Contains the hardware abstraction layer and low-level operation implementations for the various peripherals. The low-level functions assign meaningful names to register-level manipulations; the hardware abstraction provide operations one level above this, grouping these low-level functions
-into routines that achieve a meaningful action or state of the peripheral.
-
-Example:
-
-- `spi_flash_ll_set_address` is a low-level function part of the hardware abstraction `spi_flash_hal_read_block`
-
-#### `arch`
-
-Contains low-level architecture operations and definitions, including those for customizations (can be thought of on the same level as the low-level functions of `hal`).
-This can also contain files provided by the architecture vendor.
-
-Example:
-
-- `xt_set_exception_handler`
-- `riscv_global_interrupts_enable`
-- `ERI_PERFMON_MAX`
-
-#### `esp_common`
-
-Contains hardware-agnostic definitions, constants, macros, utilities, 'pure' and/or algorithmic functions that is useable by all other components (that is, barring there being a more appropriate component to put them in).
-
-Example:
-
-- `BIT(nr)` and other bit manipulation utilities in the future
-- `IDF_DEPRECATED(REASON)`
-- `ESP_IDF_VERSION_MAJOR`
-
-#### `soc`
-
-Contains description of the underlying hardware: register structure, addresses, pins, capabilities, etc.
-
-Example:
-
-- `DR_REG_DPORT_BASE`
-- `SOC_MCPWM_SUPPORTED`
-- `uart_dev_s`
-
-#### `esp_rom`
-
-Contains headers, linker scripts, abstraction layer, patches, and other related files to ROM functions.
-
-Example:
-
-- `esp32.rom.eco3.ld`
-- `rom/aes.h`
-
-### `G1` Components
-
-#### `spi_flash`
-
-SPI flash device access implementation.
-
-#### `freertos`
-
-FreeRTOS port to targets supported by ESP-IDF.
-
-#### `log`
-
-Logging library.
-
-#### `heap`
-
-Heap implementation.
-
-#### `newlib`
-
-Some functions n the standard library are implemented here, especially those needing other `G1` components.
-
-Example:
-
-- `malloc` is implemented in terms of the component `heap`'s functions
-- `gettimeofday` is implemented in terms of system time in `esp_system`
-
-#### `esp_system`
-
-Contains implementation of system services and controls system behavior. The implementations
-here may take hardware resources and/or decide on a hardware state needed for support of a system service/feature/mechanism.
-Currently, this encompasses the following, but not limited to:
-
-- Startup and initialization
-- Panic and debug
-- Reset and reset reason
-- Task and interrupt watchdogs
-
-#### `esp_hw_support`
-
-Contains implementations that provide hardware operations, arbitration, or resource sharing, especially those that
-is used in the system. Unlike `esp_system`, implementations here do not decide on a hardware state or takes hardware resource, acting
-merely as facilitator to hardware access. Currently, this encompasses the following, but not limited to:
-
-- Interrupt allocation
-- Sleep functions
-- Memory functions (external SPIRAM, async memory, etc.)
-- Clock and clock control
-- Random generation
-- CPU utilities
-- MAC settings
-
-### `esp_hw_support` vs `esp_system`
-
-This section details list some implementations and the reason for placing it in either `esp_hw_support` or `esp_system`.
-
-#### `task_wdt.c` (`esp_system`) vs  `intr_alloc.c` (`esp_hw_support`)
-
-The task watchdog fits the definition of taking and configuring hardware resources (wdt, interrupt) for implementation of a system service/mechanism.
-
-This is in contrast with interrupt allocation that merely facilitates access to the underlying hardware for other implementations -
-drivers, user code, and even the task watchdog mentioned previously!
-
-#### `crosscore_int.c` (`esp_system`)
-
-The current implementation of crosscore interrupts is tightly coupled with a number of interrupt reasons
-associated with system services/mechanisms: REASON_YIELD (scheduler), REASON_FREQ_SWITCH (power management)
-REASON_PRINT_BACKTRACE (panic and debug).
-
-However, if an implementation exists that makes it possible to register an arbitrary interrupt reason - a
-lower level inter-processor call if you will, then this implementation is a good candidate for `esp_hw_support`.
-The current implementation in `esp_system` can then just register the interrupt reasons mentioned above.
-
-#### `esp_mac.h`, `esp_chip_info.h`, `esp_random.h` (`esp_hw_support`)
-
-The functions in these headers used to be in `esp_system.h`, but have been split-off.
-However, to maintain backward compatibility, `esp_system.h` includes these headers.
-
-The remaining functions in `esp_system.h` are those that deal with system behavior, such
-as `esp_register_shutdown_handler`, or are proxy for other system components's APIs such as
-`esp_get_free_heap_size`.
-
-The functions split-off from `esp_system.h` are much more hardware manipulation oriented such as:
-`esp_read_mac`, `esp_random` and `esp_chip_info`.

-// How It Works
-// ************
-
-// 1. Components Overview
-// ======================
-
-// Xtensa has useful feature: TRAX debug module. It allows recording program execution flow at run-time without disturbing CPU.
-// Exectution flow data are written to configurable Trace RAM block. Besides accessing Trace RAM itself TRAX module also allows to read/write
-// trace memory via its registers by means of JTAG, APB or ERI transactions.
-// ESP32 has two Xtensa cores with separate TRAX modules on them and provides two special memory regions to be used as trace memory.
-// Chip allows muxing access to those trace memory blocks in such a way that while one block is accessed by CPUs another one can be accessed by host
-// by means of reading/writing TRAX registers via JTAG. Blocks muxing is configurable at run-time and allows switching trace memory blocks between
-// accessors in round-robin fashion so they can read/write separate memory blocks without disturbing each other.
-// This module implements application tracing feature based on above mechanisms. It allows to transfer arbitrary user data to/from
-// host via JTAG with minimal impact on system performance. This module is implied to be used in the following tracing scheme.
-
-//                                                        ------>------                                         ----- (host components) -----

-
-// In general tracing goes in the following way. User application requests tracing module to send some data by calling esp_apptrace_buffer_get(),
-// module allocates necessary buffer in current input trace block. Then user fills received buffer with data and calls esp_apptrace_buffer_put().
-// When current input trace block is filled with app data it is exposed to host and the second block becomes input one and buffer filling restarts.
-// While target application fills one TRAX block host reads another one via JTAG.
-// This module also allows communication in the opposite direction: from host to target. As it was said ESP32 and host can access different TRAX blocks
-// simultaneously, so while target writes trace data to one block host can write its own data (e.g. tracing commands) to another one then when
-// blocks are switched host receives trace data and target receives data written by host application. Target user application can read host data
-// by calling esp_apptrace_read() API.
-// To control buffer switching and for other communication purposes this implementation uses some TRAX registers. It is safe since HW TRAX tracing
-// can not be used along with application tracing feature so these registers are freely readable/writeable via JTAG from host and via ERI from ESP32 cores.
-// Overhead of this implementation on target CPU is produced only by allocating/managing buffers and copying of data.
-// On the host side special OpenOCD command must be used to read trace data.
-
-// 2. TRAX Registers layout
-// ========================
-
-// This module uses two TRAX HW registers to communicate with host SW (OpenOCD).
-//  - Control register uses TRAX_DELAYCNT as storage. Only lower 24 bits of TRAX_DELAYCNT are writable. Control register has the following bitfields:
-//   | 31..XXXXXX..24 | 23 .(host_connect). 23| 22..(block_id)..15 | 14..(block_len)..0 |
-//    14..0  bits - actual length of user data in trace memory block. Target updates it every time it fills memory block and exposes it to host.
-//                  Host writes zero to this field when it finishes reading exposed block;
-//    21..15 bits - trace memory block transfer ID. Block counter. It can overflow. Updated by target, host should not modify it. Actually can be 2 bits;
-//    22     bit  - 'host data present' flag. If set to one there is data from host, otherwise - no host data;
-//    23     bit  - 'host connected' flag. If zero then host is not connected and tracing module works in post-mortem mode, otherwise in streaming mode;
-// - Status register uses TRAX_TRIGGERPC as storage. If this register is not zero then current CPU is changing TRAX registers and
-//   this register holds address of the instruction which application will execute when it finishes with those registers modifications.
-//   See 'Targets Connection' setion for details.
-
-// 3. Modes of operation
-// =====================
-
-// This module supports two modes of operation:
-//  - Post-mortem mode. This is the default mode. In this mode application tracing module does not check whether host has read all the data from block
-//    exposed to it and switches block in any case. The mode does not need host interaction for operation and so can be useful when only the latest
-//    trace data are necessary, e.g. for analyzing crashes. On panic the latest data from current input block are exposed to host and host can read them.
-//    It can happen that system panic occurs when there are very small amount of data which are not exposed to host yet (e.g. crash just after the
-//    TRAX block switch). In this case the previous 16KB of collected data will be dropped and host will see the latest, but very small piece of trace.
-//    It can be insufficient to diagnose the problem. To avoid such situations there is menuconfig option
-//    CONFIG_APPTRACE_POSTMORTEM_FLUSH_THRESH
-//    which controls the threshold for flushing data in case of panic.
-//  - Streaming mode. Tracing module enters this mode when host connects to target and sets respective bits in control registers (per core).
-//    In this mode before switching the block tracing module waits for the host to read all the data from the previously exposed block.
-//    On panic tracing module also waits (timeout is configured via menuconfig via CONFIG_APPTRACE_ONPANIC_HOST_FLUSH_TMO) for the host to read all data.
-
-// 4. Communication Protocol
-// =========================
-
-// 4.1 Trace Memory Blocks
-// -----------------------
-
-// Communication is controlled via special register. Host periodically polls control register on each core to find out if there are any data available.
-// When current input memory block is filled it is exposed to host and 'block_len' and 'block_id' fields are updated in the control register.
-// Host reads new register value and according to it's value starts reading data from exposed block. Meanwhile target starts filling another trace block.
-// When host finishes reading the block it clears 'block_len' field in control register indicating to the target that it is ready to accept the next one.
-// If the host has some data to transfer to the target it writes them to trace memory block before clearing 'block_len' field. Then it sets
-// 'host_data_present' bit and clears 'block_len' field in control register. Upon every block switch target checks 'host_data_present' bit and if it is set
-// reads them to down buffer before writing any trace data to switched TRAX block.
-
-// 4.2 User Data Chunks Level
-// --------------------------
-
-// Since trace memory block is shared between user data chunks and data copying is performed on behalf of the API user (in its normal context) in
-// multithreading environment it can happen that task/ISR which copies data is preempted by another high prio task/ISR. So it is possible situation
-// that task/ISR will fail to complete filling its data chunk before the whole trace block is exposed to the host. To handle such conditions tracing
-// module prepends all user data chunks with header which contains allocated buffer size and actual data length within it. OpenOCD command
-// which reads application traces reports error when it reads incomplete user data block.
-// Data which are transffered from host to target are also prepended with a header. Down channel data header is simple and consists of one two bytes field
-// containing length of host data following the header.
-
-// 4.3 Data Buffering
-// ------------------
-
-// It takes some time for the host to read TRAX memory block via JTAG. In streaming mode it can happen that target has filled its TRAX block, but host
-// has not completed reading of the previous one yet. So in this case time critical tracing calls (which can not be delayed for too long time due to
-// the lack of free memory in TRAX block) can be dropped. To avoid such scenarios tracing module implements data buffering. Buffered data will be sent
-// to the host later when TRAX block switch occurs. The maximum size of the buffered data is controlled by menuconfig option
-// CONFIG_APPTRACE_PENDING_DATA_SIZE_MAX.
-
-// 4.4 Target Connection/Disconnection
-// -----------------------------------
-
-// When host is going to start tracing in streaming mode it needs to put both ESP32 cores into initial state when 'host connected' bit is set
-// on both cores. To accomplish this host halts both cores and sets this bit in TRAX registers. But target code can be halted in state when it has read control
-// register but has not updated its value. To handle such situations target code indicates to the host that it is updating control register by writing
-// non-zero value to status register. Actually it writes address of the instruction which it will execute when it finishes with
-// the registers update. When target is halted during control register update host sets breakpoint at the address from status register and resumes CPU.
-// After target code finishes with register update it is halted on breakpoint, host detects it and safely sets 'host connected' bit. When both cores
-// are set up they are resumed. Tracing starts without further intrusion into CPUs work.
-// When host is going to stop tracing in streaming mode it needs to disconnect targets. Disconnection process is done using the same algorithm
-// as for connecting, but 'host connected' bits are cleared on ESP32 cores.
-
-// 5. Module Access Synchronization
-// ================================
-
-// Access to internal module's data is synchronized with custom mutex. Mutex is a wrapper for portMUX_TYPE and uses almost the same sync mechanism as in
-// vPortCPUAcquireMutex/vPortCPUReleaseMutex. The mechanism uses S32C1I Xtensa instruction to implement exclusive access to module's data from tasks and
-// ISRs running on both cores. Also custom mutex allows specifying timeout for locking operation. Locking routine checks underlaying mutex in cycle until
-// it gets its ownership or timeout expires. The differences of application tracing module's mutex implementation from vPortCPUAcquireMutex/vPortCPUReleaseMutex are:
-// - Support for timeouts.
-// - Local IRQs for CPU which owns the mutex are disabled till the call to unlocking routine. This is made to avoid possible task's prio inversion.
-//   When low prio task takes mutex and enables local IRQs gets preempted by high prio task which in its turn can try to acquire mutex using infinite timeout.
-//   So no local task switch occurs when mutex is locked. But this does not apply to tasks on another CPU.
-//   WARNING: Priority inversion can happen when low prio task works on one CPU and medium and high prio tasks work on another.
-// WARNING: Care must be taken when selecting timeout values for trace calls from ISRs. Tracing module does not care about watchdogs when waiting
-// on internal locks and for host to complete previous block reading, so if timeout value exceeds watchdog's one it can lead to the system reboot.
-
-// 6. Timeouts
-// ===========
-
-// Timeout mechanism is based on xthal_get_ccount() routine and supports timeout values in microseconds.
-// There are two situations when task/ISR can be delayed by tracing API call. Timeout mechanism takes into account both conditions:
-// - Trace data are locked by another task/ISR. When wating on trace data lock.
-// - Current TRAX memory input block is full when working in streaming mode (host is connected). When waiting for host to complete previous block reading.
-// When wating for any of above conditions xthal_get_ccount() is called periodically to calculate time elapsed from trace API routine entry. When elapsed
-// time exceeds specified timeout value operation is canceled and ESP_ERR_TIMEOUT code is returned.

-

-
-            NOTE: Once a digest slot is revoked, it can never be used again to verify an image
-            This can lead to permanent bricking of the device, in case all keys are revoked
-            because of signature verification failure.
