If SD card is present -- try to boot from it first. If no -- try to boot Android from eMMC.

This series seems to switch from "standard" Linux boot to Android Linux boot, rather than allowing a fallback from one to the other. Yes? If so, that's a problem. Thanks!

It still tries to run Linux boot from SD card first:
"run mmcboot;" \
and if it fails, it tries to run Android from eMMC:
"run emmc_android_boot; " \
If that's a problem for some boards and you want them to run standard Linux from eMMC, I can try to rework that patch to choose automatically, which one to run (Linux or Android), e.g. using $partitions and $partitions_android environment variables. Or we can add some global CONFIG_ANDROID option to choose between distributions. Which one would be better?
