12d903a650 io_bus is split out into pio_bus and dma_bus so that any device
can specify either independently.

python/m5/objects/Device.py:
    io_bus is split out into pio_bus and dma_bus so that any device
    can specify either independently.
    dma_bus defaults to point to whatever pio_bus uses.

b64eae5e52 Changes for getting FreeBSD to run.
SConscript:
    Added more files to compile: dev/pcifake.cc, dev/isa_fake.cc, kern/freebsd/freebsd_system.cc, kern/freebsd/freebsd_events.cc.
arch/alpha/isa_traits.hh:
    Added constant for argument register 2 as it is needed by FreebsdSystem::doCalibrateClocks().
cpu/exec_context.hh:
cpu/o3/alpha_cpu.hh:
    Replaced htoa()s with gtoh() and htog().
cpu/o3/fetch_impl.hh:
cpu/simple/cpu.cc:
    Replaced htoa() with gtoh().
dev/disk_image.cc:
    Replaced htoa()s with letoh()s.
dev/ide_ctrl.cc:
    Got rid of magic numbers.
    Added IdeChannel and IdeRegType type names where necessary.
dev/ide_ctrl.hh:
    Got rid of unnecessary macros.
    Changed RegType_t to IdeRegType.
    Changed bmi_regs to allow accessing registers by name instead of just by array index.
    Added IdeChannel enum type to use in place of bool variables which were used to specify IDE channel.
dev/ide_disk.cc:
    Rewrote IdeDisk::read and IdeDisk::write functions to specify registers by name instead of indexing through an array.
dev/ide_disk.hh:
    Updated command register struct.
dev/ns_gige.cc:
dev/ns_gige.hh:
    Made ReadConfig and WriteConfig begin with a lower-case letter.
    writeConfig() now takes a pointer to data as a parameter instead of a copy of data.
dev/pciconfigall.cc:
    writeConfig() now takes a pointer to data as a parameter instead of a copy of data.
dev/pcidev.cc:
    Cleaned up readConfig() and writeConfig() functions.
dev/pcidev.hh:
    Added macros to make code that works with the BARs (base adress registers) more readable. writeConfig() now takes a pointer to data.
dev/pcireg.h:
    Changed PCIConfig struct to make accessing elements more straight forward. Removed type 1 (for PCI-to-PCI bridges) PCI configuration space struct since it is not used.
dev/rtcreg.h:
    Added macros for bit fields in RTC status registers A & B.
dev/sinic.cc:
    Function name change: WriteConfig --> writeConfig.
    writeConfig() now takes a pointer to data instead of a copy of data.
    The accessing of elements of PCIConfig structure is updated.
dev/sinic.hh:
    Function name change: WriteConfig --> writeConfig.
    writeConfig() now takes a pointer to data instead of a copy of data.
dev/tsunami_io.cc:
    Added implementation of new RTC and PIT classes.
dev/tsunami_io.hh:
    Added classes for RTC and PIT modules.
dev/tsunamireg.h:
    Added macros for DMA ports used by Tsunami-Tru64.
dev/uart8250.cc:
    Got rid of a magic number.
    Transmit (Tx) interrupts should clear upon a read of the Interrupt ID register.
dev/uart8250.hh:
    Added comments and macros dealing with the UART Interrupt ID register.
kern/linux/linux_system.cc:
    Replaced htoa() with htog().
python/m5/objects/Pci.py:
    PciFake is a python class for Pci Devices that do nothing.
python/m5/objects/Tsunami.py:
    TsunamiFake was renamed as IsaFake.
sim/system.cc:
    Replaced htoa()s with htog()s.
dev/isa_fake.cc:
    New BitKeeper file ``dev/isa_fake.cc''
    TsunamiFake was renamed as IsaFake.
dev/isa_fake.hh:
    New BitKeeper file ``dev/isa_fake.hh''

bd3e3c0230 forgot a change in the previous commit. the ide controller
doesn't have its own interrupt functions

dev/ide_ctrl.hh:
    oops. we don't have our own interrupt functions anymore
    we get them from the base class.

b031888038 Use parameter structs for initialization so it's easier
to add new devices.  Abstract the Platform more so that
it is unnecessary to know know platform specifics for
interrupting or translating PCI DMA addresses.

dev/ide_ctrl.cc:
    convert to parameter struct for initialization
    use the interrupt functions in the PciDev base class
    convert from tsunami to using platform
    We don't need an interrupt controller here.
dev/ide_ctrl.hh:
    don't use Tsunami, use Platform
    make the IdeDisk a friend so that it can access my plaform
    convert to parameter struct for construction
dev/ide_disk.cc:
    don't use tsunami references, but platform references
dev/ns_gige.cc:
    Convert to parameter struct for initialzation. Use code in
    base class for interrupts so we don't need to know anything
    about the platform. Don't need an IntrControl *.
dev/ns_gige.hh:
    We don't need a Tsunami * anymore
    convert to a parameter struct for construction
dev/pcidev.cc:
    deal with new parameter struct
dev/pcidev.hh:
    - Move all of the configuration parameters into a param struct
    that we can pass into the constructor.
    - Add a Platform * for accessing new generic interrupt post/clear
    and dma address translation fuctions
    - Create functions for posting/clearing interrupts and translating
    dma addresses
dev/platform.cc:
    have default functions that panic on pci calls
dev/platform.hh:
    don't make the pci stuff pure virtual, but rather provide
    default implementations that panic.  Also, add dma address
    translation.
dev/tsunami.cc:
    this-> isn't necessary here.
    add pci address translation
dev/tsunami.hh:
    implement the pciToDma address translation
