The access to ICC_BPR1_EL1 in gicv3_cpu_init is faulting for some
reason. do_hyp_trap is then access current-> but it is too soon to do
that, hence a data abort occurs which is what I was seeing.

This is on a fast model with the boot-wrapper, perhaps the "firmware"
failed to setup something?

BTW, ICC_BPR1_EL1 is the secure alias of the NS version of the register.
Why not just use the NS version directly?

Ian.
