Hm. Having these as just DDR_... seems like it would lead to confusion
if there are other DDR controllers that get added later. But I'm not
too picky either way.

These got added to ops.h in commit 2f1d4899321be so you don't need to
specify them here anymore.

What names would you suggest? DDR_DENALI_... looks too long :)
The names have been taken from the docs, I've just prefixed them with DDR_.

It's such a generic macro and not Denali or even SDRAM specific. So it really
should be no problem to keep it as is.
Just my 0.02$.

I wasn't talking about DDR_GET_VAL. I meant having the DDR registers
defines just as "DDR_START", "DDR_START_SHIFT", etc could be confusing
later.
But I don't really see a need to change it at the moment. We can
prefix the with something else if a conflicting DDR controller ever
shows up.

No need to separate this function out, just drop it into
platform_init(). Also no need for the seqouia_mac* variables - they
were in ebony to handle the cuboot vs. openbios variants. For
sequoia, you can just pull the values straight from the bd_t in
sequoia_fixups()

As we discussed on IRC, this needs to explicitly match one of the
compatible properties in the Sequoia DTS file. Otherwise it won't
probe your PLB and find anything.

Same as above, just corrected the plb bus entry in the sequoia_of_bus array
It should be "ibm,plb4" instead of "ibm,plb". The original bamboo code has the
same problem.

This is obviously nothing urgent given that the ifdef already existed, but
this looks like it really should be a runtime check instead. Multiplatform
kernels will require it (if/whenever that becomes a priority for 44x).

Yep, indeed. It's on my todo list, hopefully before 2.6.24. Don't
think we need to hold up 440EPx in the meantime, since it's a slightly
larger issue. Thanks for the reminder!
