Some ARM32_PMAP_NEW-related cleanup: * Define a new "MMU type", ARM_MMU_SA1. While the SA-1's MMU is basically compatible with the generic, the SA-1 cache does not have a write-through mode, and it is useful to know have an indication of this. * Add a new PMAP_NEEDS_PTE_SYNC indicator, and try to evaluate it at compile time. We evaluate it like so: - If SA-1-style MMU is the only type configured -> 1 - If SA-1-style MMU is not configured -> 0 - Otherwise, defer to a run-time variable. If PMAP_NEEDS_PTE_SYNC might evaluate to true (SA-1 only or run-time check), then we also define PMAP_INCLUDE_PTE_SYNC so that e.g. assembly code can include the necessary run-time support. PMAP_INCLUDE_PTE_SYNC largely replaces the ARM32_PMAP_NEEDS_PTE_SYNC manual setting Steve included with the original new pmap. * In the new pmap, make pmap_pte_init_generic() check to see if the CPU has a write-back cache. If so, init the PT cache mode to C=1,B=0 to get write-through mode. Otherwise, init the PT cache mode to C=1,B=1. * Add a new pmap_pte_init_arm8(). Old pmap, same as generic. New pmap, sets page table cacheability to 0 (ARM8 has a write-back cache, but flushing it is quite expensive). * In the new pmap, make pmap_pte_init_arm9() reset the PT cache mode to C=1,B=0, since the write-back check in generic gets it wrong for ARM9, since we use write-through mode all the time on ARM9 right now. (What this really tells me is that the test for write-through cache is less than perfect, but we can fix that later.) * Add a new pmap_pte_init_sa1(). Old pmap, same as generic. New pmap, does generic initialization, then resets page table cache mode to C=1,B=1, since C=1,B=0 does not produce write-through on the SA-1.
