[U-Boot] mainline u-boot on radxarock (rockchip rk3188) from SDcard

[Trevor Woerner]

Hello,

I am able to generate a bootable image (bootloader, parameter, kernel,
filesystem) for my radxarock (pro) on an SDcard if I use the bootloader from
https://github.com/radxa/u-boot-rockchip. When I try to use mainline
u-boot_2008.01 it doesn't seem to be able to find or boot from the SDcard:
