Commit-Message
Rockchips dwmmc controllers can't do dma to non-ddr addresses, like for example the soc-internal sram but during boot parts of TrustedFirmware need to be placed there from the read FIT image. So add handling for a u-boot,spl-fifo-mode to not put the mmc controllers into fifo mode for all time. The regular fifo-mode property still takes precedent and only if not set do we check for the spl-specific property.
