Support for Tsunami coming along... RTC, PIC working, UART in progress
dev/tsunami_io.cc:
PIC, PIT, RTC implementation for tsunami working so far
dev/tsunami_io.hh:
PIT, PIC, RTC implementation for tlaser working so far
dev/tsunamireg.h:
Added RTC defines
kern/linux/linux_system.cc:
wrote cycle frequency into variable so linux doesn't probe for it.
The support exists, but it takes two seconds of time to do on a real
machine, so forever in the simulator.
