[kvm-unit-tests,v2,00/10] powerpc: updates, P10, PNV support

Message

Since v1 series, I fixed the sleep API and implementation in patch 2
as noted by Thomas. Added usleep and msleep variants to match [um]delay
we already have.

Also some minor tidy ups and fixes mainly with reporting format in the
sprs test rework.

And added PowerNV support to the harness with the 3 new patches at the
end because it didn't turn out to be too hard. We could parse the dt to
get a console UART directly for a really minimal firmware, but it is
better for us to have a test harness like this that can also be used for
skiboot testing.

Thanks,
Nick

I'll send out one more series, I have a couple of fixes for PowerNV code
(I didn't make the OPAL call to set interrupts little endian for LE
builds, for one). I'll wait for a week or so for more feedback though.

Thanks,
Nick
