From: Heiko Stuebner Date: Tue, 19 Nov 2019 11:04:01 +0000 (+0100) Subject: rockchip: dwmmc: add handling for u-boot, spl-fifo-mode X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=c8dd0e42d709c9734f313c547d0707e27ca0de51;p=u-boot.git rockchip: dwmmc: add handling for u-boot, spl-fifo-mode 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.
