[RockPro64] Upstream U boot doesn't work for SDcard and USB

[adam900710]

Hi,

I'm trying to port RockPro64 board to Archlinux ARM.

The idbloader and trust part is mostly easy to handle, as it's unrelated to distro.

However for the bootloader, upstream U-boot only partly works, eth and boot seems to work, but sdcard failed to be recognized.

For Rock64, PKGBUILD just uses upstream U-boot, I'm wondering is it OK to use rockchip uboot other than upstream one, and package it to something like uboot-rockpro64?

Thanks.
