+ * 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).
