Just a quick comment, otherwise tested on my udoo quad/dual..
diff --git a/include/configs/udoo.h b/include/configs/udoo.h index 910bf01..f93b67a 100644 --- a/include/configs/udoo.h +++ b/include/configs/udoo.h @@ -11,6 +11,10 @@

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?
