[PATCH] xtensa: remove extra header files

rather lengthy patch removes all those files.  Unfortunately, there were
many dependencies that needed to be updated, so this patch touches quite a
few source files.

- *	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).

- *  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.

- *  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
- *		:
- *		:
- *
- *		window_spill4	// spill windows of some_function's callers; preserves a0..a3 only;
- *				// to use window_spill{8,12} in this example function we'd have
- *				// to increase space allocated by the entry instruction, because
- *				// 16 bytes only allows call4; 32 or 48 bytes (+locals) are needed
- *				// for call8/window_spill8 or call12/window_spill12 respectively.
- *		:
- *
- *		retw
- *
- *		window_spill_common	// instantiates code used by window_spill4
- *
- *
- *  On entry:
- *	none (if window_spill4)
- *	stack frame has enough space allocated for call8 (if window_spill8)
- *	stack frame has enough space allocated for call12 (if window_spill12)
- *  On exit:
- *	 a4..a15 clobbered (if window_spill4)

- *  In this case, it may be appropriate for the OS to verify at run-time

- *  [Guidelines as to which release is compatible with which are not

- *  OSKit documentation for all releases -- compatibility is also highly
- *  dependent on which HAL features are used.  Each release is usually

- *  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

- *  Device addresses.

- *  Note:  for endianness-independence, use 32-bit loads and stores for all
- *  register accesses to Ethernet, DUART and LED devices.  Undefined bits
- *  may need to be masked out if needed when reading if the actual register
- *  size is smaller than 32 bits.
- *
- *  Note:  XT2000 bus byte lanes are defined in terms of msbyte and lsbyte
- *  relative to the processor.  So 32-bit registers are accessed consistently
- *  from both big and little endian processors.  However, this means byte
- *  sequences are not consistent between big and little endian processors.
- *  This is fine for RAM, and for ROM if ROM is created for a specific
- *  processor (and thus has correct byte sequences).  However this may be
- *  unexpected for Flash, which might contain a file-system that one wants
- *  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.
- *  Someone implementing an endianness-independent Flash file system will
- *  likely handle this byte-swapping issue in the Flash driver software.
