After more testing, it appears the eMMC was somehow corrupted.  I
initially used Tim's copy-to-emmc.sh script to set up the eMMC -- I
got a couple of lock reversal errors (still haven't figured out how to
disable WITNESS via the make cmd line) and saw this issue.

I then rewrote the img to /dev/mmcsd1 and it was able to bring up the
eMMC.  I tried Tim's script again and this time didn't get lock
reversal errors and it's also able to boot from eMMC.

So I don't know if there was some corruption ... I'll keep testing.

But anyway, I can now boot 10-STABLE from eMMC.

Thanks!
