[ARM] nommu: adjust headers for !MMU ARM systems
Majorily based on Hyok Choi's patches, this fixes up the asm-arm header files for mmuless systems. Over and above Hyok's patches: - nommu.h merged into mmu.h (it's only a structure) - nommu_context.h is essentially the same as mmu_context.h, but without the MM switching code. so there's no point having separate files. Also, in memory.h, there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the configuration scripts. Other files have minor formatting changes, but are essentially the same. Hyok's original patches were signed off thusly: Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
