X-Git-Tag: v2017.05-rc1~49^2~40
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2e2a8dc635f5ca3be9d96759a905ede73f1baf33;p=u-boot

i.MX6UL: isiot: Add modeboot env via board_late_init

Add runtime, modeboot env which is setting mmcboot, or
nandboot based on the bootdevice so-that conditional
macros b/w MMC and NAND for CONFIG_BOOTCOMMAND should
be avoided in config files.
