2016-08-26ARM: Move SYS_CACHELINE_SIZE over to KconfigTom Rini
This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all cases we are mirroring the values used by the Linux Kernel here. Also, so long as (and in this case, it is true) we implement flushes in hunks that are no larger than the smallest implementation (and given that we mirror the Linux Kernel, again we are fine) it is OK to align higher. The biggest changes here are that we always use 64 bytes for CPU_V7 even if for example the underlying core is only 32 bytes (this mirrors Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the Linux Kernel) as we do not need multi-platform support (to this degree) and only the Cavium ThunderX 88xx series has a use for such large alignment.

2015-08-12ARM: cache: implement a default weak flush_cache() functionWu, Josh
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 <josh.wu@atmel.com>
2015-08-12ARM: cache: add an empty stub function for invalidate/flush dcacheWu, Josh
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.
