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).

Sorry, I don't know what I was thinking when I wrote that expression in
response to the last time you posted this patch. I think it should be
simply:

#define CONFIG_ENV_OFFSET ((4096 * 1024) - CONFIG_ENV_SIZE)

Feel free to fix this up when applying; no need to repost.
