gem5/dev/tsunami.cc
Ali Saidi 54b49f933a rewrote uart and renamed console.cc to simconsole to reduce confusion
base/traceflags.py:
    removed TsunamiUart/TlaserUart and added a plain Uart
dev/alpha_console.cc:
    updated for new simconsole
dev/platform.hh:
    added a uart member to platform
dev/simconsole.cc:
dev/simconsole.hh:
    removed lots of legacy code, it should all be ours now.
    converted tabs to 8 spaces
    added our copyright
dev/tsunami.cc:
    uses simconsole.hh rather than console.hh
dev/tsunami_cchip.cc:
dev/tsunami_io.cc:
    never needed console.hh
dev/tsunami_io.hh:
    this does need eventq.hh and it just happend to be working whenn console.hh was
    included everywhere
dev/tsunamireg.h:
    added a couple more 8250/16550 uart defines
dev/uart.cc:
    new uart code, rewritten to support both tlaser and tsunami (both a 8250 and 8530
    uart).
dev/uart.hh:
    updated for new uart, legacy code removed
