Error: Illegal access to ... when flashing custom board with own configuration/device tree
Hello,
I want to upgrade my hardware to new openstlinux kirkstone release november 2022.
First test on eval board was successful.
I have written custom device tree files and compiling for tf-a, u-boot, fip and kernel is fine.
However when I try to flash my image flashlayout to my custom board I get a "ERROR: Illegal access to 0xfffffff0:"
See following for complete output:

What is wrong in my configuration or device tree?
Error messages come from tf-a, not sure if it is related to u-boot and fip.
Any suggestion is appreciated! Thanks!
