I've started posting this series well in advance to get it into 6.0 and yet it seems like it may be missing it due to organisational issues (no real complaints were found with patches but Philippe seems to like more review that does not seem to happen as nobody is interested). Looks like David is waiting for an ack from Philippe but will be away next week so if this is not resolved now it may be too late on Monday. To avoid that:

David, could you please send an ack before you leave for the last two patches so it could get committed via some other tree while you're away?

Philippe, if you can't ack the vt82c686 patches now are you OK with taking the whole series via your tree before the freeze? That would give you some more days to review and it could always be reverted during the freeze but if it's not merged now I'll have to wait until the summer to get it in again which would be another long delay. I don't think this will get more reviews unless it's in master and people can start using and testing it better.


Since David seems to be away for this week before seeing my mail asking for an ack from him, now this can only get in by Philippe or Peter. (David said before he'd be OK with the series if Philippe acked it so I think that can count as an implicit ack and it could always be reverted before the releease.)

Philippe, do you have anything against this to get merged now? If not please send a pull or ack it so it has a chance to be in 6.0 or tell if you still intend to do anything about it before the freeze. This series was on the list since January and the remaining parts you did not take are here since February 22nd and the version after your first review since two weeks so it would be nice to sort this out and not block it any further without a good reason.


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.
