 The boot order is fixed and is SPI->eMMC->SD
 So if a bootloader exists on the eMMC it will boot from it.
 The u-boot installed will try to boot from the sdcard using u-boot
distro boot mechanism but it will not work for us as EFI is broken on
it. (It might work if you use kernel.bin and compile it with
LINUX_BOOT_ABI).

 From sd but my eMMC is blank.
