Subject: net/designware: ensure device private data is DMA aligned.
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1c848a258600490f6964597b92b69a107af141d6;p=u-boot.git

net/designware: ensure device private data is DMA aligned.

struct dw_eth_dev contains fields which are accessed via DMA, so make sure it
is aligned to a dma boundary. Without this I see:
    ERROR: v7_dcache_inval_range - start address is not aligned - 0x7fb677e0
