DMA buffer cache invalidation requires that buffers have cache-aligned buffer locations and sizes. Use memalign() and ALLOC_CACHE_ALIGN_BUFFER() to ensure this.
On Tegra at least, without this fix, the following fail commands fail in u-boot-master/ext4, but succeeded at the branch's branch point in u-boot/master. With this fix, the commands work again:
ext2ls mmc 0:1 / ext2load mmc 0:1 /boot/zImage
