Hi all,

Using the latest boot-wrapper and the Foundation Model (build 11.10.22),
mainline fails to boot with defconfig due to what appears to be a pointer
authentication failure in the kernel. Disabling CONFIG_ARM64_PTR_AUTH makes
the problem disappear.

I'm passing "--arm-v8.4 --no-sve --cores=2" to the model.

I'll try to look into this today, but thought it was worth posting in
case anybody else gets the chance as well.

Cheers,

Will
