-The latest support policy for ESP-IDF can be found at [https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md](https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md)
-
-Support Period Policy
-=====================
-
-Each ESP-IDF major and minor release (V4.0, V4.1, etc) is supported for
-18 months after the initial stable release date.
-
-Supported means that the ESP-IDF team will continue to apply bug fixes,
-security fixes, etc to the release branch on GitHub, and periodically
-make new bugfix releases as needed.
-
-Users are encouraged to upgrade to a newer ESP-IDF release before the
-support period finishes and the release becomes End of Life (EOL). It is
-our policy to not continue fixing bugs in End of Life releases.
-
-Pre-release versions (betas, previews, `-rc` and `-dev` versions, etc)
-are not covered by any support period. Sometimes a particular feature is
-marked as \"Preview\" in a release, which means it is also not covered
-by the support period.
-
-The ESP-IDF Programming Guide has information about the
-[different versions of ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/versions.html)
-(major, minor, bugfix, etc).
-
-Long Term Support releases
---------------------------
-
-Some releases (starting with ESP-IDF V3.3) are designated Long Term
-Support (LTS). LTS releases are supported for 30 months (2.5 years)
-after the initial stable release date.
-
-A new LTS release will be made at least every 18 months. This means
-there will always be a period of at least 12 months to upgrade from the
-previous LTS release to the following LTS release.
-
-Example
--------
-
-ESP-IDF V3.3 was released in September 2019 and is a Long Term Support
-(LTS) release, meaning it will be supported for 30 months until February
-2022.
-
-- The first V3.3 release was `v3.3` in September 2019.
-- The ESP-IDF team continues to backport bug fixes, security fixes,
-  etc to the release branch `release/v3.3`.
-- Periodically stable bugfix releases are created from the release
-  branch. For example `v3.3.1`, `v3.3.2`, etc. Users are encouraged to
-  always update to the latest bugfix release.
-- V3.3 bugfix releases continue until February 2022, when all V3.3.x
-  releases become End of Life.
-
-Existing Releases
------------------
-
-ESP-IDF release V3.3 and all newer releases will follow this support
-period policy.  The support period for each release will be announced
-when the release is made.
-
-For releases made before the support period policy was announced,
-the following support periods apply:
-
-- ESP-IDF V3.1.x and V3.2.x will both be supported until October 2020.
-- ESP-IDF V3.0.9 (planned for October 2019) will be the last V3.0
-  bugfix release. ESP-IDF V3.0.x is End of Life from October 2019.
-- ESP-IDF versions before V3.0 are already End of Life.

-     *   2) Write plaintext digest based on plaintext bootloader
-     *   3) Generate flash encryption key and write to EFUSE.
-     *   4) Encrypt flash in-place including bootloader, then digest,
-     *      then app partitions and other encrypted partitions
-     *   5) Burn EFUSE to enable flash encryption (FLASH_CRYPT_CNT)
-     *   6) Burn EFUSE to enable secure boot (ABS_DONE_0)
-     *
-     * If power failure happens during Step 1, probably the next boot will continue from Step 2.
-     * There is some small chance that EFUSEs will be part-way through being written so will be
-     * somehow corrupted here. Thankfully this window of time is very small, but if that's the
-     * case, one has to use the espefuse tool to manually set the remaining bits and enable R/W
-     * protection. Once the relevant EFUSE bits are set and R/W protected, Step 1 will be skipped
-     * successfully on further reboots.
-     *
-     * If power failure happens during Step 2, Step 1 will be skipped and Step 2 repeated:
-     * the digest will get re-written on the next boot.
-     *
-     * If power failure happens during Step 3, it's possible that EFUSE was partially written
-     * with the generated flash encryption key, though the time window for that would again
-     * be very small. On reboot, Step 1 will be skipped and Step 2 repeated, though, Step 3
-     * may fail due to the above mentioned reason, in which case, one has to use the espefuse
-     * tool to manually set the remaining bits and enable R/W protection. Once the relevant EFUSE
-     * bits are set and R/W protected, Step 3 will be skipped successfully on further reboots.
-     *
-     * If power failure happens after start of 4 and before end of 5, the next boot will fail
-     * (bootloader header is encrypted and flash encryption isn't enabled yet, so it looks like
-     * noise to the ROM bootloader). The check in the ROM is pretty basic so if the first byte of
-     * ciphertext happens to be the magic byte E9 then it may try to boot, but it will definitely
-     * crash (no chance that the remaining ciphertext will look like a valid bootloader image).
-     * Only solution is to reflash with all plaintext and the whole process starts again: skips
-     * Step 1, repeats Step 2, skips Step 3, etc.
-     *
-     * If power failure happens after 5 but before 6, the device will reboot with flash
-     * encryption on and will regenerate an encrypted digest in Step 2. This should still
-     * be valid as the input data for the digest is read via flash cache (so will be decrypted)
-     * and the code in secure_boot_generate() tells bootloader_flash_write() to encrypt the data
-     * on write if flash encryption is enabled. Steps 3 - 5 are skipped (encryption already on),
-     * then Step 6 enables secure boot.
