Implement basic part of SA-1110/SA-1100
Basic implementation of DEC/Intel SA-1100/SA-1110 chips emulation. Implemented: - IRQs - GPIO - PPC - RTC - UARTs (no IrDA/etc.) - OST reused from pxa25x Everything else is TODO (esp. PM/idle/sleep!) - see the todo in the hw/strongarm.c Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
