If we don't DMA-align buffers we pass to FAT, it will align them itself. This behaviour likely should be deprecated in favor of CONFIG_BOUNCE_BUFFER, but that's a task for another series. For the meantime, don't bother aligning the buffer unless we had been doing so in the past. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
