Subject: imx: mx7dsabresd: move mmc_get_env_devno to soc code
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=62d8cce9f37c12ff92a47414484997a74d038440;p=u-boot.git

imx: mx7dsabresd: move mmc_get_env_devno to soc code

Move mmc_get_env_devno to soc.c and rename to mmc_get_env_dev to
match the one in common/env_mmc.c.
Introduce a weak function board_mmc_get_env_dev. Different
boards can implement this according to sdhc controller which
is used by the board.
