This series adds a Kconfig to disable cache maintenance operations on
a coherent architectures. And disable cache flush/invalidate ops for
SPL/U-Boot code running on A53 core of AM654 SoC(which is IO coherent)

v2:
Allow flush_dcache_all() and invalidate_dcache_all() that are used
before enabling/disabling dcache by U-Boot and are special case.


Vignesh Raghavendra (2):
