RE: UART, pxa250

Vaibhav, Carl,

One thing that Brian noticed is that PocketPC on the h3900 is very
sensitive to scribbling on dram -- or dram not being refreshed. It will
probably be helpful to disconnect the battery while doing bootldr work
so that you can power it off for a couple of minutes to put dram into a
zeroed state.

Regarding your previous note about the sa1100.h vs pxa250.h: we think it
would be best to use these files from the linux kernel. They do not
have the SA1100 prefix, so it is already one step towards something like
you suggested. The argument against using the corresponding files from
Linux is that it would preclude a non-gpl bootldr. Either way, the
required files should be part of the bootldr source tree and should not
have SA1100_ or PXA250_ prefixes on the defines.

It would help if Vaibhav could go through and clean up the use of the
SA1110 registers from sa1100.h.

Finally, when Brian checks in his initial changes, we're going to put a
#error directive in so that no casual users will try to compile and
install the bootldr until we're sure it is stable.
