Drivers (especially frameworks ported from Linux such as USB) expect
dma_{un}map_single() APIs to take care of cache maintenance. But this is
not the case in U-Boot and few drivers take care of flushing caches
locally. Instead add flush/invalidate calls to DMA APIs in arch specific
dma-mapping.h file so that per driver implementation of these APIs can
be avoided.I don't have all the affected hardwares. Would greatly appreciate if these patches work fine on the affected platforms.
