 Hi Alexander,

I just put your series into a run with the gitlab-CI and it seems this now 
introduced another failure in one of the avocado tests:

 https://gitlab.com/thuth/qemu/-/jobs/4171448248#L318

The "IbmPrep40pMachine.test_openbios_and_netbsd" test is failing now.

You can reproduce it manually quite easily:

 wget 
https://archive.netbsd.org/pub/NetBSD-archive/NetBSD-7.1.2/iso/NetBSD-7.1.2-prep.iso

 ./qemu-system-ppc -nographic -M 40p -boot d -cdrom NetBSD-7.1.2-prep.iso

Without your patches, this prints out "NetBSD/prep BOOT, Revision 1.9" in 
the console, but with your patches, the message does not appear anymore.

Could you please have a look?

 Thanks,
  Thomas
