Series | [v3,1/2] imx8mm: configs: add support for distro boot commands | expand |
> From: Alice Guo <alice.guo@nxp.com> > Distro Boot requires a U-Boot-specific script named boot.scr or > boot.scr.uimg which contains boot commands to boot the system. The > boot.cmd is such a file. Use mkimage to generate boot.scr or > boot.scr.uimg from boot.cmd, and the command is: > mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Distro Boot Script" -d boot.cmd boot.scr.uimg > The boot.cmd file is an example script and can be modified based on > needs. bootargs is set in this script and root uses the default value " > /dev/mmcblk1p2 rootwait rw" which can be changed by overriding mmcroot. > Reviewed-by: Peng Fan <peng.fan@nxp.com> > Signed-off-by: Alice Guo <alice.guo@nxp.com> Applied to u-boot-imx, master, thanks ! Best regards, Stefano Babic
