0dde7f5379 arm: Add control over cachability of memory regions
Add support for adjusting the L1 cache behavior by updating the MMU
configuration. The mmu_set_region_dcache_behaviour() function allows
drivers to make these changes after the MMU is set up.

It is implemented only for ARMv7 at present.

This is needed for LCD support, where we want to make the LCD frame buffer
write-through (or off) rather than write-back.

819833af39 Move architecture-specific includes to arch/$ARCH/include/asm
This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
