- * xt-xcc cannot modify the contents of a single __asm__ statement, so
- * we create single-asm versions of the syscall macros that are
- * suitable and optimal for both xt-xcc and gcc.
- *
- * Linux takes system-call arguments in registers.  The following
- * design is optimized for user-land apps (e.g., glibc) which
- * typically have a function wrapper around the "syscall" assembly
- * instruction.  It satisfies the Xtensa ABI while minizing argument
- * shifting.
- *
- * The Xtensa ABI and software conventions require the system-call
- * number in a2.  If an argument exists in a2, we move it to the next
- * available register.  Note that for improved efficiency, we do NOT
- * shift all parameters down one register to maintain the original
- * order.
- *
- * At best case (zero arguments), we just write the syscall number to
- * a2.  At worst case (1 to 6 arguments), we move the argument in a2
- * to the next available register, then write the syscall number to
- * a2.
- *
- * For clarity, the following truth table enumerates all possibilities.

- *  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.)

- *  This header file defines assembler macros of the form:
- *      <x>cacheattr_<func>
- *  where:
- *      <x> is 'i', 'd' or absent for instruction, data
- *              or both caches; and
- *      <func> indicates the function of the macro.
- *
- *  The following functions are defined:
- *
- *  icacheattr_get
- *      Reads I-cache CACHEATTR into a2 (clobbers a3-a5).
- *
- *  dcacheattr_get
- *      Reads D-cache CACHEATTR into a2 (clobbers a3-a5).
- *      (Note:  for configs with a real CACHEATTR register, the
- *       above two macros are identical.)
- *
- *  cacheattr_set
- *      Writes both I-cache and D-cache CACHEATTRs from a2 (a3-a8 clobbered).
- *      Works even when changing one's own code's attributes.
- *
- *  icacheattr_is_enabled  label
- *      Branches to \label if I-cache appears to have been enabled
- *      (eg. if CACHEATTR contains a cache-enabled attribute).
- *      (clobbers a2-a5,SAR)
- *
- *  dcacheattr_is_enabled  label
- *      Branches to \label if D-cache appears to have been enabled
- *      (eg. if CACHEATTR contains a cache-enabled attribute).
- *      (clobbers a2-a5,SAR)
- *
- *  cacheattr_is_enabled  label
- *      Branches to \label if either I-cache or D-cache appears to have been enabled
- *      (eg. if CACHEATTR contains a cache-enabled attribute).
- *      (clobbers a2-a5,SAR)
- *
- *  The following macros are only defined under certain conditions:
- *
- *  icacheattr_set      (if XCHAL_HAVE_MIMIC_CACHEATTR || XCHAL_HAVE_XLT_CACHEATTR)
- *      Writes I-cache CACHEATTR from a2 (a3-a8 clobbered).
- *
- *  dcacheattr_set      (if XCHAL_HAVE_MIMIC_CACHEATTR || XCHAL_HAVE_XLT_CACHEATTR)
- *      Writes D-cache CACHEATTR from a2 (a3-a8 clobbered).

- *  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).

- *  find_ms_setbit
- *
- *  This macro finds the most significant bit that is set in <as>

- *  The index counts starting at zero for the lsbit, so the return
- *  value ranges from <base>-1 (no bit set) to <base>+31 (msbit set).
- *
- *  Parameters:
- *      <ad>    destination address register (any register)
- *      <as>    source address register
- *      <at>    temporary address register (must be different than <as>)
- *      <base>  constant value added to result (usually 0 or 1)
- *  On entry:
- *      <ad> = undefined if different than <as>
- *      <as> = value whose most significant set bit is to be found
- *      <at> = undefined
- *      no other registers are used by this macro.
- *  On exit:
- *      <ad> = <base> + index of msbit set in original <as>,
- *           = <base> - 1 if original <as> was zero.
- *      <as> clobbered (if not <ad>)

- *  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.

- *  window_spill{4,8,12}
- *
- *  These macros spill callers' register windows to the stack.
- *  They work for both privileged and non-privileged tasks.
- *  Must be called from a windowed ABI context, eg. within
- *  a windowed ABI function (ie. valid stack frame, window
- *  exceptions enabled, not in exception mode, etc).
- *
- *  This macro requires a single invocation of the window_spill_common
- *  macro in the same assembly unit and section.
- *
- *  Note that using window_spill{4,8,12} macros is more efficient
- *  than calling a function implemented using window_spill_function,
- *  because the latter needs extra code to figure out the size of
- *  the call to the spilling function.
- *
- *  Example usage:
- *
- *              .text
- *              .align  4
- *              .global some_function
- *              .type   some_function,@function
- *      some_function:
- *              entry   a1, 16
- *              :
- *              :

- *  In this case, it may be appropriate for the OS to verify at run-time
- *  whether XTHAL_RELEASE_* and Xthal_release_* are compatible.
- *  [Guidelines as to which release is compatible with which are not
- *  currently provided explicitly, but might be inferred from reading
- *  OSKit documentation for all releases -- compatibility is also highly
- *  dependent on which HAL features are used.  Each release is usually
- *  backward compatible, with very few exceptions if any.]

- *  System call like services offered by the simulator host.
- *  These are modeled after the Linux 2.4 kernel system calls
- *  for Xtensa processors.  However not all system calls and
- *  not all functionality of a given system call are implemented,
- *  or necessarily have well defined or equivalent semantics in
- *  the context of a simulation (as opposed to a Unix kernel).
- *
- *  These services behave largely as if they had been invoked
- *  as a task in the simulator host's operating system
- *  (eg. files accessed are those of the simulator host).
- *  However, these SIMCALLs model a virtual operating system
- *  so that various definitions, bit assignments etc
- *  (eg. open mode bits, errno values, etc) are independent
- *  of the host operating system used to run the simulation.
- *  Rather these definitions are specific to the Xtensa ISS.
- *  This way Xtensa ISA code written to use these SIMCALLs
- *  can (in principle) be simulated on any host.
- *
- *  Up to 6 parameters are passed in registers a3 to a8
- *  (note the 6th parameter isn't passed on the stack,
- *   unlike windowed function calling conventions).
- *  The return value is in a2.  A negative value in the
- *  range -4096 to -1 indicates a negated error code to be
- *  reported in errno with a return value of -1, otherwise
- *  the value in a2 is returned as is.

-/* 16550 UART DEVICE REGISTERS
-   The XT2000 board aligns each register to a 32-bit word but the UART device only uses
-   one byte of the word, which is the least-significant byte regardless of the
-   endianness of the core (ie. byte offset 0 for little-endian and 3 for big-endian).
-   So if using word accesses then endianness doesn't matter.
-   The macros provided here do that.

- *  to use for multiple processor configurations (eg. the Flash might contain
- *  the Ethernet card's address, endianness-independent application data, etc).
- *  That is, byte sequences written in Flash by a core of a given endianness
- *  will be byte-swapped when seen by a core of the other endianness.
