I have now tested this, and annoyingly UEFI and the kernel seem
to disagree about enumeration order. That is, if QEMU creates
them in the code in the order 0x09050000 (uart 2), 0x09000000 (uart 1),
then they appear in the dtb with uart 1 first, and the kernel enumerates
them as ttyAMA0 being uart 1 and ttyAMA1 being uart 2, but UEFI
outputs to uart 2...
thanks
