13f8dc981f make the cache access latency a parameter that is based on bus
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

dev/ns_gige.cc:
    The ethernet dev uses two BARs, and the first bars size was being set
    incorrectly.
dev/tsunamireg.h:
    I don't know why we were using the superpage as the PCI memory addr.
    Changed and works correctly with detailed boot.

4768c72964 Fix the RTC code so it is in the cchip, only interrupt processors that
are present

dev/tsunami_cchip.cc:
    Only need to interrupt processors that are there
    Move RTC interrupt code into a function
dev/tsunami_cchip.hh:
    Make a RTC interrupt function, move variables out of public scope
dev/tsunami_io.cc:

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
dev/tsunami_io.cc:

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.
