rk3568 boot fail with TF-A binary

[Alexander Shiyan]

Hello All.

I'm trying to use the open source TF-A implementation for the Rockchip
rk3568 CPU:
https://github.com/ARM-software/arm-trusted-firmware/commit/9fd9f1d024872b440e3906eded28037330b6f422

The barebox starts to launch, but an error occurs, the meaning of
which I don’t know how to interpret.
If I use Rockchip's RKBIN binary this doesn't happen.

Has anyone tried running something like this?
What does this error mean?
