The platform_setup1 and the memory layout is bogus. I have to do my stuff 
currently without hardware ... (I burned one device). So one can say that I 
haven't done too much.

However, the infrastructure has been laid (it compiles without errors), the 
abstraction of PXA specific things has been done. The following files could 
be mostly correct:

pxa2x0/var/current/include/hal_cache.h (copied from verde, modified)
pxa2x0/var/current/include/hal_diag.h
pxa2x0/var/current/include/hal_mm.h (copied from verde, modified)
pxa2x0/var/current/include/hal_pxa2x0.h (copied from sa11x0, then delete lots 
of stuff and added another lot of stuff, I have the feeling that most defines 
for the PXA-builtin hardware registers are not used)
pxa2x0/var/current/include/hal_var_ints.h (seems ok except HAL_PLATFORM_RESET, 
no RTC stuff as in other platforms)
pxa2x0/var/current/include/plf_stub.h (copied from somewhere (sa11x0?))
pxa2x0/var/current/include/var_io.h (almost empty)
pxa2x0/var/current/src/pxa_misc.c (irq stuff seems not ok, e.g. 
hal_interrupt_acknowledge, but to my knowledge redboot won't use IRQs?)
pxa2x0/var/current/tests/* totally bogus
