From: Alastair D'Silva <alastair@d-silva.org>
This series addresses a few issues discovered in how we flush caches: 1. Flushes were truncated at 4GB, so larger flushes were incorrect. 2. Flushing the dcache in arch_add_memory was unnecessary
This series also converts much of the cache assembler to C, with the aim of making it easier to maintain.
Alastair D'Silva (6): powerpc: Allow flush_icache_range to work across ranges >4GB powerpc: define helpers to get L1 icache sizes powerpc: Convert flush_icache_range & friends to C powerpc: Chunk calls to flush_dcache_range in arch_*_memory powerpc: Remove 'extern' from func prototypes in cache headers powerpc: Don't flush caches when adding memory
