Subject: rockchip: rk3399: enable spl-fifo-mode for sdmmc
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=5c606ca35c421faf42499f78ce4a4e7745d53df6;p=u-boot.git

rockchip: rk3399: enable spl-fifo-mode for sdmmc

adapting commit fa2047c47310 ("rockchip: rk3328: enable spl-fifo-mode
for emmc and sdmmc") for rk3399.
Since mmc to sram can't do dma, add patch to prevent aborts transferring
TF-A parts.
