[v10] Pegasos2 emulation

[PATCH v10 0/7] Pegasos2 emulation

Posted by BALATON Zoltan 4 years, 8 months ago

Hello,

This is adding a new PPC board called pegasos2. More info on it can be
found at:

https://osdn.net/projects/qmiga/wiki/SubprojectPegasos2

Currently it needs a firmware ROM image that I cannot include due to
original copyright holder (bPlan) did not release it under a free
licence but I have plans to write a replacement in the future. With
the original board firmware it can boot MorphOS now as:

qemu-system-ppc -M pegasos2 -cdrom morphos.iso -device ati-vga,romfile="" -serial stdio

then enter "boot cd boot.img" at the firmware "ok" prompt as described
in the MorphOS.readme. To boot Linux use same command line with e.g.
-cdrom debian-8.11.0-powerpc-netinst.iso then enter
"boot cd install/pegasos"

The last patch adds the actual board code after previous patches
adding VT8231 and MV64361 system controller chip emulation.

Regards,
BALATON Zoltan

I've applied 1..5 to a new ppc-for-6.1 branch.  Sorry it didn't make
it for 6.0, I just didn't have time to look this over until too late.

Thanks but maybe you should wait if the dropped original first patch can 
be reviewed now and brought back. It would be easier for me to resubmit 
whole series rebased than port the dropped patch on top of a partly 
applied series. Also first patches without the last two is not much useful 
as the vt8231 model these add would not be used by anything else.

Ok, I've dropped your patches from ppc-for-6.1 again, and I'll wait
for the next posting.

Should've waited for the outcome of the review of the patch in question as 
it turns out it was voted against so the ones you dropped will stay. Sorry 
for the churn, I've posted v11 with all patches again changing last two 
patches according to your review. Let me know if anything else is needed.

Thank you,
