[RFC PATCH 0/2] Pegasos2 emulation

From: BALATON Zoltan
Subject: [RFC PATCH 0/2] Pegasos2 emulation
Date: Wed, 06 Jan 2021 23:43:25 +0100


This is adding a new PPC board called pegasos2 currently posted as RFC
because it depends on not yet merged VT8231 emulation currently on the


and may need some changes like a test case but I'm posting it now for
getting feedback on what's needed to merge this. More info on it can
be found at:


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
that 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"

Patch 2 adds the actual board code after patch 1 adding MV64361 system
controller chip. The mv643xx.h header file is taken from Linux and
produces a bunch of checkpatch warnings due to different formatting
rules it follows, I'm not sure we want to adopt it or keep it as it is
given that it does not appear any more in recent Linux versions so we
could reformat it as it's unlikely to get updated in the future.
