Sort of a minor nit, but I'm not actually sure these registers are read-only :( I know the documentation doesn't describe how to change them, but in PCI-E EndPoint mode they are read by the host so the firmware must be able to change them to reflect the firmware running on the endpoint.. Which is to say, I suppose the bootloader could program them to something else if it wanted to. That said, in practice obviously they will not be changed, but maybe there is another ID register you can read?
