				MMU
  ----------------------------------------------------------------------*/

/*
 *  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).
