Subject: mmc: sdhci: add the DMA select for SDMA
|

X-Git-Url: http://git.denx.de/?p=u-boot.git;a=commitdiff_plain;h=804c7f422169212e92530e1ddaf74bf1ca9ebfa1

mmc: sdhci: add the DMA select for SDMA
|
|
|
|
In host-control register, DMA select bit field is present.
|
|
BUt in sdhci.c, didn't select for DMA.
|
|
if set CONFIG_MMC_SDMA, we need to set SDMA-select bit.
