Subject: [PATCH] rockchip: rk3399: enable spl-fifo-mode for sdmmc
Date: Wed, 15 Apr 2020 08:55:24 +0530	[thread overview]
Message-ID: <20200415032524.2534-1-deepakdas.linux@gmail.com> (raw)

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.
