Some additional comments:
* Did you actually try setting CPM_IRQ_OFFSET to a non-zero value? I'm
guessing this doesnt work since you are not offset the irq passed into
the other functions. For example, if CPM_IRQ_OFFSET is 64, will
cpm2_mask_irq() work?
* what is SA_NOTHREAD all about?

Jason, why did you bother to implement these functions, they dont
provide any value for us?
It looks like startup() & shutdown() are only used in IRQ probing code
or code in which enable/disable will be used instead.

Nothing. In fact, they are
Some feedback on the patches:
* I'm not going to accept the printing of caches enabled, etc. If you
want to do this add sysfs attributes to the CPU. That is more useful
going forward and we dont have to do it for every board then. (Plus we
can add other attributes)

Oh my ... I'm more worried about the high number of TLB misses
in 2.6 compared to 2.4. That's really bad. How did you instrument

While I can specify a place for you to get precompiled binaries for
MPC7448, I can suggest grabbing crosstool from:
http://www.kegel.com/crosstool/
There is a 7450 config which will work for MPC7448.

That was rather a _factor_ of "100-or-so" less.

That one is still pending.
There are other issues in 8xx which are probably related to it, as follows.

ppc32: Adds necessary cpu init to use USB on LITE5200 Platform
To use external peripheral on MPC5200, some clocking registers
and port-muxing must be done. Since this is platform specific,
it's placed the platform support file. This particular patch
is for USB support on the LITE5200.

Hi all,
This series of patch changes all the MPC52xx related code
to use platform bus and ppc_sys instead of OCP. It's
divided in several patches that represents "steps" in
the conversion. However the intermediate states might
not be functionnal.
