Hello Mark,
I managed to boot and install a 9.2.1. Here is what I have used for
that :
* qemu, David's 2.7 branch, plus Ben's patch "v2 ppc: Fix support
for odd MSR combinations".
* openbios, github's HEAD + the patch your patch from :
https://www.coreboot.org/pipermail/openbios/2015-June/008722.html
* iso, the os9.osi from
http://c-obrien.org/qemu-os9/testing/
There are a couple of qemu errors :
dbdma_unassigned_rw: use of unassigned channel 14
dbdma_unassigned_flush: use of unassigned channel 14
CUDA: unknown command 0x24
and invalids read/write on SPRs but it didn't cause any issue in the guest
at installation time or later at runtime. I did not try network though.
So mainline only misses your forth patch. Looking really good !
Thanks,
C.
