Subject: imx: ventana: use common uart and i2c setup functions in SPL
X-Git-Tag: v2015.07-rc2~145
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=2089b7be2b50078ef27a26fe627173535d13e5ee;p=oweals%2Fu-boot.git

imx: ventana: use common uart and i2c setup functions in SPL

Now that uart and i2c setup functions have been moved to common.c we can
use these and remove code duplication.
