ARM: cache: implement a default weak flush_cache() function

2015-08-13T00:47:48Z

Current many cpu use the same flush_cache() function, which just call the flush_dcache_range(). So implement a weak flush_cache() for all the cpus to use. In original weak flush_cache() in arch/arm/lib/cache.c, there has some code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache() function as well. That means the original code for ARM1136 & ARM926ejs in weak flush_cache() of arch/arm/lib/cache.c is totally useless. So in this patch remove such code in flush_cache() and only call flush_dcache_range(). Signed-off-by: Josh Wu

ARM: cache: add an empty stub function for invalidate/flush dcache

2015-08-13T00:47:47Z

Since some driver like ohci, lcd used dcache functions. But some ARM cpu don't implement the invalidate_dcache_range()/flush_dcache_range() functions. To avoid compiling errors this patch adds an weak empty stub function for all ARM cpu in arch/arm/lib/cache.c. And ARM cpu still can implemnt its own cache functions on the cpu folder.
