It's an SD card. If you have any "OMAP" platform (beagleboard,
beaglebone, pandaboard) or am35x/am37x or similar platforms SPL should
hang like that. 72MB partition (or so) on either a 2 or 4GB card.
Getting all the way up into U-Boot clears the problem away until power
cycle. That last part makes me worried...
