Re: RK3588 optee question

Hello.

Yes, everything works now.

The only thing that's unclear is that kernel loading is interrupted
when using the open source TF-A
for the RK3568. The RK3588 doesn't have this problem.
However, this is most likely a problem with the TF-A implementation,
not the barebox.

Thanks!
