ticks for the most commonly accessed devices.

dev/baddev.cc:
    Get rid of the constant cache access latency.
    For unimportant devices, don't add any latency.

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

de5fa66714 Rewrote interrupt code to handle masking correctly and changed every
interrupt to use a different subnumber since both devices could
interrupt at the same time and we don't want to loose one.

dev/tsunami_cchip.cc:
    rewrote interrupt code to handle interrupt mask clearing correctly
dev/tsunami_cchip.hh:
    changed (post/clear)DRIR to use a interrupt number rather than a vecotr

0035440536 Linux boots with no devices
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.
