From: Peng Fan Date: Fri, 21 Dec 2018 06:21:34 +0000 (+0000) Subject: imx8qxp: mek: default enable SPL X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=018e3fd2d1a73044154056faf0c69d57c81af58f;p=u-boot.git imx8qxp: mek: default enable SPL Enable SPL for i.MX8QXP MEK, and currently use SPL FIT. The SPL enable SPL_DM to use MMC/PINCTRL/POWER DOMAIN/CLK. Note: SPL FIT could not support secure boot chain, because i.MX8/8X only support i.MX container format. This container format has not been upstreamed, so we use FIT for now. When SPL container supported, we could switch to that.
