Nice hack :)
But not something mergeable as it strictly relies on the specific format
of the interrupt map on that platform :) I have a generic parser on the
way, it's hot and will be released for public consumption later today or
this week-end along with the rest of the irq patches.
I'll need you guys to help porting the few embedded boards already in
arch/powerpc.

Of course. We've also lined Andy Fleming up to help
with some 85xx parts, and Kim Phillips to help with
some 83xx parts. (Hi guys!)
BTW and for (your) references, I will follow up with
the complete MPC8641 HPCN DTS file here!
Thanks,
jdl

Folks,
For reference, here is the complete MPC8641 HPCN Device Tree Source
file that we have been using. Please feel free to comment on it.
(And yes, I know we need to change the ethernet "address" property
names -- that's on the Big To Do List still (for all the FSL boards)).
Thanks!
jdl
PS -- This version matches up with assuming the
"Use IRQ and senses from OF-tree on 8641hpcn"
patch has been applied.
