For what it's worth, I went to use the firmware from 7.9 as stated in
part of the readme (since the README states both 8.0 and 7.9), and I
used the ATF from 4.19.35_1.1.0, and it booted once I commented out
the sdhc2 cd-gpio lines.

It seems like 8.0 doesn't work quite right.

I am not sure why the GPIO for card detect isn't working for me.  I
get an error -123 (ENOMEDIUM).  I tried enabling SPL_DM_GPIO without
any success, so i just disabled the cd pin, and it boots now.
