You can always be the first.

No, but there is documentation for the ASIC as well as all the rest of
the hardware on the handhelds.org site.

The processor support is all there.

You would need a startup routine that expects the parameters that the
bootloader will pass to it. I have one for the SA11x0 that would only
need a couple of lines changing to work with the PXA255.

Drivers to talk to the ASIC.

Driver for MQ1100 graphics controller.

Ok. The reason for asking was to know whether you wanted to boot out
of flash or to mount a filesystem from CF.

We don't have a driver for flash chips in the tree right now.

The only handhelds that are supported are the H36xx and the J72x by
hpcarm.

I don't know of anyone except HP that provides enough documentation
to be able to do a port.

If I could choose any handheld at the moment it would be the H5550,
it has plenty of SDRAM and flash, the fastest speed grade PXA255
and a graphics accelerator.
