the following hooks have been added to the ehci Ctlr structore to handle cache coherency (on arm): void* (*tdalloc)(ulong,int,ulong); void* (*dmaalloc)(ulong); void (*dmafree)(void*); void (*dmaflush)(int,void*,ulong); tdalloc() is used to allocate descriptors and the periodic frame schedule array. on arm, this needs to return uncached memory. tdalloc()ed memory is never freed. dmaalloc()/dmafree() is used for io buffers. this can return cached memory when when hardware maintains cache coherency (pc) or dmaflush() is provided to flush/invalidate the cache (zynq), otherwise needs to return uncached memory. dmaflush() is used to flush/invalidate the cache. the first argument tells us if we need to flush (non zero) or invalidate (zero). uncached.h is gone now. this change makes the handling explicit.
