I'm fine with processing the changes through your tree. Most of the items
with conflicts are in this series, so hopefully it won't be too messy (outside
of some Makefile and Kconfig changes which are much easier to merge)
after this. So, should I base changes on:
http://git.kernel.org/?p=linux/kernel/git/jwboyer/powerpc-4xx.git;a=shortlog;h=refs/heads/next
or:
http://git.kernel.org/?p=linux/kernel/git/benh/powerpc.git;a=shortlog;h=refs/heads/next

There are some important questions on code organization which it would
probably be a good idea to discuss at some point -- in particular what I
should do about the device drivers. Pretty much every driver except for
the ethernet is particular to this platform. IIRC some of the embedded
platforms have the SOC drivers in the platforms directory -- but it doesn't
seem like you've done this with 4xx so I was gonna just place them in
the appropriate drivers/* directory. The other question is that there are
a number of patches which involve communication which a somewhat
substantial firmware layer. You can get an idea of the existing patch's
code organization by looking at:
http://git.kernel.org/?p=linux/kernel/git/ericvh/bluegene.git;a=commit;h=bee9f329eeef6c8eb95c35de4c5d22a0c05a1b3e

Its important to point out that I am going through and cleaning up as I
go, so not everything from that patch will make the cut as is (or perhaps
even at all) -- but that should help identify where potential conflicts are
as well as potentially out of place code.

Yeah, I wondered about that, its just I hate patch series intro messages with
no patch, and I figured this was a good way out of it. It also adds
the relevant
info as far as mailing lists and wiki pages where folks can go for more info --
but if folks have a problem with it I'll kill it until we get
everything else in.
