X-Git-Tag: v2017.05-rc1~49^2~57
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=04cb0d3e3fcee139fdf84b4d0da28bc1a184fa1d;p=oweals%2Fu-boot.git

imx: mx7ulp_evk: enable mmc/regulator support

Enable MMC support.
The fsl sdhc driver needs regulator to enable power, so enable
regulator support.

And bootcmd and more env.
