[Robert Nelson]

Just a quick comment, otherwise tested on my udoo quad/dual..

So ^ this forces use to include "u-boot.img" in a "FAT" partition..
For extX, you'd have to add:

#define CONFIG_SPL_EXT_SUPPORT

But, this also breaks if you had dd'ed SPL/u-boot.img..

U-Boot SPL 2015.10-rc1-00001-gc195aa3 (Aug 03 2015 - 17:48:55)
spl_register_fat_device: fat register err - -1
spl_load_image_fat: error reading image u-boot.img, err - -1
spl: mmc: no boot mode left to try
### ERROR ### Please RESET the board ###

sudo dd if=./u-boot/SPL of=${DISK} seek=1 bs=1k
sudo dd if=./u-boot/u-boot.img of=${DISK} seek=69 bs=1k

Shouldn't we just not enable either and do like the wandboard and just
dd SPL/u-boot.img?
