Re: [PATCH 1/4] mmc: bfin_sdh: limit mmc DMA segment len to 1 for bf518.

[Sonic Zhang <sonic.adi@gmail.com>]

Hi Chris,

Could you review this series of patches for Blackfin on-chip SD
controller? The head file and new BF60x machine code have been merged
upstream. These patches are necessary to get SD driver built on BF60x.

Thanks

Sonic Zhang
