2011-12-08ARM: LPAE: MMU setup for the 3-level page table formatCatalin Marinas
This patch adds the MMU initialisation for the LPAE page table format. The swapper_pg_dir size with LPAE is 5 rather than 4 pages. A new proc-v7-3level.S file contains the TTB initialisation, context switch and PTE setting code with the LPAE. The TTBRx split is based on the PAGE_OFFSET with TTBR1 used for the kernel mappings. The 36-bit mappings (supersections) and a few other memory types in mmu.c are conditionally compiled. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
