From 0dd259a1b13554947d813ed315dc860cee67fb8e Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Fri, 24 Feb 2017 15:45:19 +0530 Subject: [PATCH] i.MX6UL: isiot: 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.
