Necessary steps are likely to be:

	0) Adapt hpcarm to deal with non-StrongARM CPUs
	1) Reuse PXA255 code from evbarm
	2) Write the machdep code to boot off bootldr
	3) Support H5xxx ASIC, Linux seems to have the code

Anyone knows on which machine is NetBSD loaded with bootldr? All I can
see in hpcarm relies on hpcboot.exe, while evbarm mainly uses redboot...

I have done 0+1 some time ago, but haven't had time since then.

AFAIK none of the PXA based PDAs is supported. Only older StrongARM ones.
One reason might be that these small keyboard-less toys are not terribly
useful in real life ;-).
