I finally was able to complete this series and test it satisfactorily.
This required some hacking to the OMAP UART debugging code so it would
stop fighting against me and forcefully collaborate.
Now that I've got a PandaBoard I'm getting rather grumpy with some of
that code... Some patches touching that area from me are to be expected
in the near future.
But in the mean time I think you can complete the p2v branch with the
following:

I also have 2 additional patches for this branch to follow:

It should at least build with 6651/1 in place. The only fight
remaining is against the (imho misguided) attempt to select the debug
port based on the machine ID. I normally end up hard-coding the
addresses.

Not if you do try to load the kernel somewhere else in memory to
exercize its ability to live with a different phys offset.

That's what I ended up doing too, but something better and IMHO simpler
could be done, which would also be fully position independent.

I've rebased my 2 patches on top of your latest p2v branch. You may
pull them from:
git://git.linaro.org/people/nico/linux p2v
Or if you prefer I can put them in the patch system.

I'd like to wait for Catalin to respond on the phys_addr_t patch - which
allows 64-bit phys addresses. Obviously that's going to have an impact
on the p2v code and I'd rather someone else had the job of working out
what to do about the T2 code.

OK.
Thinking ahead a bit, what changes would be needed? Obviously, there
can't be a machine with all its RAM above the 4G limit or it wouldn't be
able to run without the MMU on. And the p2v/v2p conversion macros can
only be used on the direct mapped memory i.e. the non highmem memory
which is likely to be all located below that 4G limit. In that case the
fixup code shouldn't be affected, right?

I rebased my revised patches on top of Will's in your p2v branch and
pushed the result to the above repository.

Now rebased on top of p2v-stable, and includes the lookup_machine_type()
cleanup patch.
Nicolas Pitre (3):
ARM: P2V: Thumb2 support
ARM: ignore mdesc->boot_params if out of range
ARM: fold lookup_machine_type() into setup_machine()
