It is NOT at all wise to put any uboot on SPI until you have thoroughly tested it
Be aware the the uboot package for SPI is a bit different,,,, uboot at 6M and idbloader 'expanded'
One way to test,, on emmc, save mbr, save 1st 16M, blank (/dev/zero) 1st 16M, restore mbr
Then, only the uboot on SD is available, to boot emmc use a small (tiny) SD
with ONLY uboot on it (idbloader, uboot.itb OR idbloader,uboot.img,trust.img,,, mainline vrs bsp)
You will find that uboot (for pbp) is NOT at all mature
