Please drop these GIC_CPU_MASK_SIMPLE from the interrupt specifiers,
they do not mean anything with GICv3.

Are you sure you do need this? Can't your firmware be fixed to correctly
program CNTFRQ_EL0?

Same remark about the mask.

Looks nice. Is there any peripheral capable of generating MSIs on this SoC?

Thanks,
