Some hardware requires the data buffers to be cacheline-aligned to make sure DMA operations can be properly executed.
This patch uses the ALLOC_CACHE_ALIGN_BUFFER macro to allocate buffers with proper alignment. The same was already done for EFI partitions in commit f75dd58 "part_efi: dcache: allocate cacheline aligned buffers".

I just noticed that the same patch was already posted by Eric Nelson back in March. Anatolij Gustschin just applied it to u-boot-staging/agust@denx.de.
