[RFT] ppc64 OpenBIOS

[Andreas Färber]

Hello,

Except for some fs/iso9660/ issues, ppc64 guests are booting for me  
with the last five OpenBIOS patches posted.

You can find them together with the config change to use fs/grubfs/  
here:

git://repo.or.cz/openbios/afaerber.git ppc64-boot

Please test your favorite ppc64 kernels and images with obj-ppc64/ 
openbios-qemu.elf!

If I don't hear of regressions, I'll commit those patches. Once that  
is done and the iso9660 issues hopefully fixed, I would ask for Blue  
to commit openbios-ppc and openbios-ppc64 blobs to QEMU. I'll then  
prepare a QEMU patch to switch the default qemu-system-ppc64  
ppc_newworld.c BIOS from openbios-ppc to openbios-ppc64.

Thanks,
Andreas

What are the issues?

Passes my simple tests. The only problem is that building forthstrap
on a 64 bit host fails.

I think openbios-ppc should be renamed to openbios-ppc32 for
consistency with Sparc naming.

It still hangs after the "Trying" line, as reported in the "ppc64 boot  
issues" thread.
The exact cause is as of yet unknown.

Right. Should we hack switch-arch as an interim solution to make it  
work?

No objection from my side.

I'd prefer a real fix, unless the problem persists.
