GCC removing support for PPC 601

How will NetBSD handle premature removal of backends?  Is there any
plan to upgrade the current GCC compiler, or will NetBSD attempt to
move to PCC or LLVM for kernel compilation?

This will drop support for PPC601, RSC, POWER1 and POWER2 (the last 3
used by rs6000 port).

I set off a minor storm by accident here
http://gcc.gnu.org/ml/gcc/2010-06/msg00811.html.  Granted, I'm not the
most diplomatic of people.

Regards,
Kevin

Problems with NetBSD 5.0.x stable evbppc/ev64260

	We have a board that is based on the ev64260 evaluation board.  We have a working port for our board on
NetBSD4.  However, trying to move forward to NetBSD5, I ran into some problems that had no apparent
solution in the ev64260 sources.

	1) clock setup -- I had to directly initialize ticks_per_sec and ns_per_tick.
	2) IPL_SERIAL is now equal to IPL_HIGH, and as such when I attempted to add a serial console (on board
16550a), arch/powerpc/marvell/extinter.c would not establish the interrupt as it was equal to
IPL_HIGH (set in sys/intr.h -- so I wasn't comfortable just modifying that... so I modified extinter.c).
	3) I've hacked my way around these two issues, but now, init processes /.profile, and will print 1 fifo's
worth of output.  Can't break into ddb with a break, and the shell gets no input.
	So, I looked at current, and it has moved quite a bit (all good looking changes, but probably a bit much for us
to take at this point).  Is the board port working for NetBSD5?  And any ideas of what I've missed (including
proper answers to my hacks above).

Thanks,
- bob

NetBSD/powerpc had a major interrupt scheme rework around 2007 of post-NB4 era.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

That's great! Congratulations!

BTW, does that mean that we also support MPC8543 and 8533 based systems now?
I have some nice Synology NAS systems in mind. :)

Yes.  When this stuff get committed, those should work.
