Thanks for the diffstat, that is very helpful as an estimate. It appears
that there is a large amount of work ahead of you in this, so by the
time you get ready for inclusion, we will most certainly require this
to be based on device tree for probing of all devices. I'd strongly
recommend that you investigate what that means for you before you port
a lot of the code to 2.6.39 or 2.6.40.
Since the timing is a bit unfortunate for you, you might want to stay
on 2.6.38 with the full port and not spend too much time on forward
porting all of it, but instead migrate the drivers to be based on
device tree properties rather than platform data, so you can submit
the drivers individually upstream.

The irqs.h and map.h are the largest by far here, and they should go
away for the most part with the move to device tree.

There is a new pinmux subsystem in the works, so you probably
end up having to write a new driver for that subsystem.

Any drivers in here should get moved to a proper place in drivers/*/
eventually, out of the subarchitecture code.

It's not clear yet what will happen in the long run to the split between
mach-* and plat-* directories. Ideally, we would not need them to be
separate if we can completely abstract the SoCs within their broader
families, but we might not get that far before you merge your platform.
What other mach-* do you expect to see in the future using plat-sirfsoc,
and how similar are they to prima2?

And these can hopefully all get moved next to the respective drivers.

For the perfmon implementation, I would recommend splitting it out of the
submission at the beginning. If it's based on perf, it should be easy to
add at a later stage. Otherwise, it's not going anywhere. If it's related
to the ARM system trace macrocell, I'd recommend posting the code now
(independent of the rest), because other people are interested in getting
that to work.

A new user space interface is always hard to establish. If you want these
to get in, you should start way ahead of the other drivers that simply
implement an existing interface.
If the gps driver is just a tty device like a serial port, it should
now be moved into drivers/tty.

These will probably all get replaced with device tree bindings.

And these can hopefully all get moved next to the respective drivers.

For the perfmon implementation, I would recommend splitting it out of the
submission at the beginning. If it's based on perf, it should be easy to
add at a later stage. Otherwise, it's not going anywhere. If it's related
to the ARM system trace macrocell, I'd recommend posting the code now
(independent of the rest), because other people are interested in getting
that to work.

A new user space interface is always hard to establish. If you want these
to get in, you should start way ahead of the other drivers that simply
implement an existing interface.
If the gps driver is just a tty device like a serial port, it should
now be moved into drivers/tty.

How does this relate to drivers/mtd?

Have you considered doing a KMS device driver instead of an old-style
frame buffer?

Ok, no problem.
