This is adding a new PPC board called pegasos2. 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
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. 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 and change formatting or keep it as it

A couple of overall comments:

* Adding yourself to MAINTAINERS for the new files would be a good
* At least some rudimentary tests would be good, though I guess that
  might be tricky with non-free firmware

I've described here what could be a test:


but I'm not sure how to implement that in qtest so if somebody helped with that that would be greatly appreciated.
