On-going 4xx porting

On-going 4xx porting

[Josh Boyer]

Hi All,

For those interested, I have a few things I'd like to focus on for
2.6.25 in regards to the current arch/powerpc 4xx porting effort.  Below
is a brief list of drivers in no particular order:

PCI support
USB (440EP(x), etc)
I2C
GPIO
NDFC
RTC

I'd also like to try and get the larger page size patches ported and
merged.  If another hugetlbfs type patch shows up, that would be good
too.  There is also the HW watchpoint support patch, and of course new
board ports.

At some point we should really be able to have a single vmlinux be
wrapped with different zImage wrappers and .dts files and have it boot
on those various boards just fine.  So I'll be looking at accomplishing
that as well.  That should make new board ports fairly easy to do.

I'll look at that stuff once again. maybe it worths to head fir compromise solution in favor of replacing 32/64 
ranges parsing func + a bunch of other things in one single step.

looks like we have code ready for that...

Stefan's approach seems pretty close

I'd rather follow platform device wrapper way.. Big NDFC of_device rework can be done anytime later.

Sure, that's fine.  You and Ben were working on it at one point, so I
figured you would look at it again.

It's mostly there, yes.  Should be pretty easy to get in :).

Agreed.

I would seriously consider that too.
