dev/tsunami.hh:
Started commenting code
dev/tsunami_cchip.cc:
removed unneccessary config files
dev/tsunami_io.cc:
Added code to see the value written
dev/tsunami_uart.cc:
conviently one of the addresses the SuperI/O southbridge can be is the same space
as the UART. This stops the simulator from panicing although it should probably be
changed a bit.
