The boot failure start with commit 2ffab9da9142 ("Merge patch series
"Firewall ATF and OP-TEE memory regions in Sitara"").

With commit 24338c81ec2f ("arm: dts: k3-binman: Use configs for
ATF/OPTEE addresses") the board still boots fine.
I have some concern that this commit is changing something, however
CONFIG_K3_ATF_LOAD_ADDR is 0x80000000, while before in the dtsi file it
was 0x70000000. I tried changing it back without any positive result,
I just got an EL3 exception.

Any more test I should do?
