Ok, thanks for the info.

I'm trying to boot from SDMMC and written SPL and u-boot.itb
(ATF+Cortex-M0) like

# dd if=spl of=/dev/mmcblk0 seek=64
# dd if=u-boot.itb of=/dev/mmcblk0 seek=512

With this ROM picked boot image from eMMC instead of SDMMC and hang at
'try to start rockusb' [1]

Do I need to loader here? and wiki [2] doesn't mention to write loader
for ARMv8 with SPL
