Guo Ren	013de2d667	csky: MMU and page table management This patch adds files related to memory management and here is our memory-layout: Fixmap : 0xffc02000 – 0xfffff000 (4 MB - 12KB) Pkmap : 0xff800000 – 0xffc00000 (4 MB) Vmalloc : 0xf0200000 – 0xff000000 (238 MB) Lowmem : 0x80000000 – 0xc0000000 (1GB) abiv1 CPU (CK610) is VIPT cache and it doesn't support highmem. abiv2 CPUs are all PIPT cache and they could support highmem. Lowmem is directly mapped by msa0 & msa1 reg, and we needn't setup memory page table for it.
