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. --HG-- extra : convert_revision : e0ed7f271ece4ed69c06af35d1b0e8ed848cd138
