* This header file defines assembler macros of the form:
* <x>cache_<func>
* where <x> is 'i' or 'd' for instruction and data caches,
* and <func> indicates the function of the macro.
*
* The following functions <func> are defined,
* and apply only to the specified cache (I or D):
*
* reset
* Resets the cache.
*
* sync
* Makes sure any previous cache instructions have been completed;
* ie. makes sure any previous cache control operations
* have had full effect and been synchronized to memory.
* Eg. any invalidate completed [so as not to generate a hit],
* any writebacks or other pipelined writes written to memory, etc.
*
* invalidate_line (single cache line)
* invalidate_region (specified memory range)
* invalidate_all (entire cache)
* Invalidates all cache entries that cache
* data from the specified memory range.
* NOTE: locked entries are not invalidated.
*
* writeback_line (single cache line)
* writeback_region (specified memory range)
* writeback_all (entire cache)
* Writes back to memory all dirty cache entries
* that cache data from the specified memory range,
* and marks these entries as clean.
* NOTE: on some future implementations, this might
* also invalidate.
* NOTE: locked entries are written back, but never invalidated.
* NOTE: instruction caches never implement writeback.
*
* writeback_inv_line (single cache line)
* writeback_inv_region (specified memory range)
* writeback_inv_all (entire cache)
* Writes back to memory all dirty cache entries
* that cache data from the specified memory range,
* and invalidates these entries (including all clean
* cache entries that cache data from that range).
* NOTE: locked entries are written back but not invalidated.
* NOTE: instruction caches never implement writeback.
*
* lock_line (single cache line)
* lock_region (specified memory range)
* Prefetch and lock the specified memory range into cache.
* NOTE: if any part of the specified memory range cannot
* be locked, a Load/Store Error (for dcache) or Instruction
* Fetch Error (for icache) exception occurs. These macros don't
* do anything special (yet anyway) to handle this situation.
*
* unlock_line (single cache line)
* unlock_region (specified memory range)
* unlock_all (entire cache)
* Unlock cache entries that cache the specified memory range.
* Entries not already locked are unaffected.
*
* coherence_on
* coherence_off
* Turn off and on cache coherence
*

/*************************** GENERIC -- ALL CACHES ***************************/
/*
* The following macros assume the following cache size/parameter limits
* in the current Xtensa core implementation:
* cache size: 1024 bytes minimum
* line size: 16 - 64 bytes
* way count: 1 - 4
*
* Minimum entries per way (ie. per associativity) = 1024 / 64 / 4 = 4
* Hence the assumption that each loop can execute four cache instructions.
*
* Correspondingly, the offset range of instructions is assumed able to cover
* four lines, ie. offsets {0,1,2,3} * line_size are assumed valid for
* both hit and indexed cache instructions. Ie. these offsets are all
* valid: 0, 16, 32, 48, 64, 96, 128, 192 (for line sizes 16, 32, 64).
* This is true of all original cache instructions
* (dhi, ihi, dhwb, dhwbi, dii, iii) which have offsets
* of 0 to 1020 in multiples of 4 (ie. 8 bits shifted by 2).
* This is also true of subsequent cache instructions
* (dhu, ihu, diu, iiu, diwb, diwbi, dpfl, ipfl) which have offsets
* of 0 to 240 in multiples of 16 (ie. 4 bits shifted by 4).
*
* (Maximum cache size, currently 32k, doesn't affect the following macros.
* Cache ways > MMU min page size cause aliasing but that's another matter.)

/*
* General notes on MMU parameters.
*
* Terminology:
* ASID = address-space ID (acts as an "extension" of virtual addresses)
* VPN = virtual page number
* PPN = physical page number
* CA = encoded cache attribute (access modes)
* TLB = translation look-aside buffer (term is stretched somewhat here)
* I = instruction (fetch accesses)
* D = data (load and store accesses)
* way = each TLB (ITLB and DTLB) consists of a number of "ways"
* that simultaneously match the virtual address of an access;
* a TLB successfully translates a virtual address if exactly
* one way matches the vaddr; if none match, it is a miss;
* if multiple match, one gets a "multihit" exception;
* each way can be independently configured in terms of number of
* entries, page sizes, which fields are writable or constant, etc.
* set = group of contiguous ways with exactly identical parameters
* ARF = auto-refill; hardware services a 1st-level miss by loading a PTE
* from the page table and storing it in one of the auto-refill ways;
* if this PTE load also misses, a miss exception is posted for s/w.
* min-wired = a "min-wired" way can be used to map a single (minimum-sized)
* page arbitrarily under program control; it has a single entry,
* is non-auto-refill (some other way(s) must be auto-refill),
* all its fields (VPN, PPN, ASID, CA) are all writable, and it
* supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
* restriction is that this be the only page size it supports).
*
* TLB way entries are virtually indexed.
* TLB ways that support multiple page sizes:
* - must have all writable VPN and PPN fields;
* - can only use one page size at any given time (eg. setup at startup),
* selected by the respective ITLBCFG or DTLBCFG special register,
* whose bits n*4+3 .. n*4 index the list of page sizes for way n
* (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
* this list may be sparse for auto-refill ways because auto-refill
* ways have independent lists of supported page sizes sharing a
* common encoding with PTE entries; the encoding is the index into
* this list; unsupported sizes for a given way are zero in the list;
* selecting unsupported sizes results in undefined hardware behaviour;
* - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

* floop, floopnez, floopgtz, floopend
*
* These macros are used for fast inner loops that
* work whether or not the Loops options is configured.
* If the Loops option is configured, they simply use
* the zero-overhead LOOP instructions; otherwise
* they use explicit decrement and branch instructions.
*
* They are used in pairs, with floop, floopnez or floopgtz
* at the beginning of the loop, and floopend at the end.
*
* Each pair of loop macro calls must be given the loop count
* address register and a unique label for that loop.
*
* Example:
*
* movi a3, 16 // loop 16 times
* floop a3, myloop1
* :
* bnez a7, end1 // exit loop if a7 != 0
* :
* floopend a3, myloop1
* end1:
*
* Like the LOOP instructions, these macros cannot be
* nested, must include at least one instruction,
* cannot call functions inside the loop, etc.
* The loop can be exited by jumping to the instruction
* following floopend (or elsewhere outside the loop),
* or continued by jumping to a NOP instruction placed
* immediately before floopend.
*
* Unlike LOOP instructions, the register passed to floop*
* cannot be used inside the loop, because it is used as
* the loop counter if the Loops option is not configured.
* And its value is undefined after exiting the loop.
* And because the loop counter register is active inside
* the loop, you can't easily use this construct to loop
* across a register file using ROTW as you might with LOOP
* instructions, unless you copy the loop register along.

* abi_entry
*
* Generate proper function entry sequence for the current ABI
* (windowed or call0). Takes care of allocating stack space (up to 1kB)
* and saving the return PC, if necessary. The corresponding abi_return
* macro does the corresponding stack deallocation and restoring return PC.
*
* Parameters are:
*
* locsize Number of bytes to allocate on the stack
* for local variables (and for args to pass to
* callees, if any calls are made). Defaults to zero.
* The macro rounds this up to a multiple of 16.
* NOTE: large values are allowed (e.g. up to 1 GB).
*
* callsize Maximum call size made by this function.
* Leave zero (default) for leaf functions, i.e. if
* this function makes no calls to other functions.
* Otherwise must be set to 4, 8, or 12 according
* to whether the "largest" call made is a call[x]4,
* call[x]8, or call[x]12 (for call0 ABI, it makes
* no difference whether this is set to 4, 8 or 12,
* but it must be set to one of these values).
*
* NOTE: It is up to the caller to align the entry point, declare the
* function symbol, make it global, etc.
*
* NOTE: This macro relies on assembler relaxation for large values
* of locsize. It might not work with the no-transform directive.
* NOTE: For the call0 ABI, this macro ensures SP is allocated or
* de-allocated cleanly, i.e. without temporarily allocating too much
* (or allocating negatively!) due to addi relaxation.
*
* NOTE: Generating the proper sequence and register allocation for
* making calls in an ABI independent manner is a separate topic not
* covered by this macro.
*
* NOTE: To access arguments, you can't use a fixed offset from SP.
* The offset depends on the ABI, whether the function is leaf, etc.
* The simplest method is probably to use the .locsz symbol, which
* is set by this macro to the actual number of bytes allocated on
* the stack, in other words, to the offset from SP to the arguments.
* E.g. for a function whose arguments are all 32-bit integers, you
* can get the 7th and 8th arguments (1st and 2nd args stored on stack)
* using:
* l32i a2, sp, .locsz
* l32i a3, sp, .locsz+4
* (this example works as long as locsize is under L32I's offset limit
* of 1020 minus up to 48 bytes of ABI-specific stack usage;
* otherwise you might first need to do "addi a?, sp, .locsz"
* or similar sequence).
*
* NOTE: For call0 ABI, this macro (and abi_return) may clobber a9
* (a caller-saved register).
*
* Examples:
* abi_entry
* abi_entry 5
* abi_entry 22, 8
* abi_entry 0, 4

/*
* XDM registers can be accessed using APB, ERI, or JTAG (via NAR).
* Address offsets for APB and ERI are the same, and for JTAG
* is different (due to the limited 7-bit NAR addressing).
*
* Here, we first provide the constants as APB / ERI address offsets.
* This is necessary for assembler code (which accesses XDM via ERI),
* because complex conversion macros between the two address maps
* don't work in the assembler.
* Conversion macros are used to convert these to/from JTAG (NAR),
* addresses, for software using JTAG.
