Tested on my Dalmore E1611 board, eMMC and SD-Card work fine, can load
a kernel off of an SD card OK, card detect works, and the env is now
stored in eMMC (end of the 2nd 'boot' sector, same as Tegra20/30).

I believe that Dalmore's eMMC "boot" sectors are 4MiB in size, so that'd
want to be (4096 - 512) * 1024) - CONFIG_ENV_SIZE. At least, that's what
"mmcinfo" told me when running our downstream U-Boot on my Dalmore.

Aside from the comments I've made, the series,
