Since we support ATF in SPL and add script for it, let's make the

Do we still need rk3399_loader_v1.08.106.bin? if u-boot.itb has ATF,
We need this for db command for now, if we enable rockusb in U-Boot, then we
don't
need db command and we don't need rk3399_loader_v1.08.106.bin
rk3399_loader_v1.08.106.bin will be there for Windows flash tool like
rkdeveloptool in Linux.
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]
In the boot rom, the eMMC has higher priority if it have firmware.
So what you need to do is override the firmware in eMMC, then you can
use SD card.
You can do this.
dd if=/dev/zero of=out count=4096
rkdeveloptool db rkxx_loader_vx.xx.bin
rkdeveloptool wl 0x40 out
rkdeveloptool rd
After this, the bootrom should not able to found firmware in eMMC, and
it will
try to find the firmware in SD card.
Thanks,

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