We may have discussed this before: AFAICT this will print 32-bit EL0 detected even if there's no 32-bit EL0 on any CPU. Should we instead print 32-bit EL0 detected on CPU X when allow_mismatched_32bit_el0 is passed? It would also give us an indication of the system configuration when people start reporting bugs.
