Subject: icorem6: Add mmc_late_init
X-Git-Tag: v2017.07-rc1~248^2~33
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=4bbd40596b52203158333cfcd56f64f92b04a7f3;p=u-boot

icorem6: Add mmc_late_init

Let the runtime code can set the mmcdev and mmcroot based
on the devno using mmc_get_env_dev instead of defining
separately in build-time configs using mmc_late_init func.
