PXA event timer

[Alexander Motin]

Hi.

While testing in QEMU calloutng on ARM platforms not ported to new
eventtimers, I've ported to them timer of PXA. I works reasonably in
QEMU, but would be nice to check it on real hardware. If somebody have
one, could you please try this patch on top of projects/calloutng branch
sources: http://people.freebsd.org/~mav/pxa_eventtimer.patch

This tool should help to test how good system works with different time
intervals: http://people.freebsd.org/~mav/testsleep.c

Thank you.
