Be carefull here. The HWUART is currently
reassigned to the bluetooth module. This can be
easily undone via /proc/GPIO. Also the HWUART is
currently configured with AFE, auto flow enabled.
See the PXA255 documentation from Intel. With
autoflow enabled, you don't have to do anything
to make use of the flow control. If you want to
undo it, adjust the patch. Review this list
archive, there is some important stuff re HWUART.
