[U-Boot] [PATCH] mx6qsabresd: Fix booting the kernel from SDHC3
commit 49ea0ff5 (mx6qsabresd: use on-board eMMC to store environment) broke booting a uImage from SDHC3.
Adapt the default environment to use CONFIG_SYS_MMC_ENV_DEV as the correct mmc node for loading the kernel, since mmcdev should not be harcoded to zero.
While at it, go back to using SDHC3 as default mmc, since we have Yocto images that generate an SD card containing U-boot,kernel and rootfs, so it is more convenient to keep using SDHC3 as it was originally.

I think you need to split the string so the macro is expanded. as: "mmcdev=" CONFIG_SYS_MMC_ENV_DEV "\0" \
On am I missing something?
