when using tftp on the smartweb board, it prints a lot of

CACHE: Misaligned operation at range [23b2e000, 23b2e100]

warnings ... fixed them.

There are 2 checkpatch warnings in this patch, for example: CHECK: Alignment should match open parenthesis + invalidate_dcache_range(macb->rx_ring_dma, + ALIGN(macb->rx_ring_dma + MACB_RX_DMA_DESC_SIZE,

But if I align this, it gets unreadable ...
