I did one more test.

It seems that the issue is some interaction between the firewall series
and commit 24338c81ec2f ("arm: dts: k3-binman: Use configs for ATF/OPTEE
addresses").

If I keep the firewall series in, and revert 24338c81ec2f, it boots.

IMO, unless we understand what is going on exactly, we should revert
both.

Suhaas: is current master working for you on the am62 SK or beagle play?
