9f8db6f446 don't handle device specific configuration stuff in the base
class.  While we're at it, very minor formatting.

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

b881408ed7 Clean up the Range class and associated usages. The code was
never clear about whether the end of the range was inclusive
or exclusive.  Make it inclusive, but also provide a RangeSize()
function that will generate a Range based on a start and a size.
This, in combination with using the comparison operators, makes
almost all usages of the range not care how it is stored.

base/range.cc:
    Make the end of the range inclusive.

    start/end -> first/last
    (end seems too much like end() in stl)
base/range.hh:
    Make the end of the range inclusive.

    Fix all comparison operators so that they work correctly with
    an inclusive range.  Also, when comparing one range to another
    with <, <=, >, >=, we only look at the beginning of the range
    beacuse x <= y should be the same as x < y || x == y.  (This wasn't
    the case before.)

    Add a few functions for making a range:
    RangeSize is start and size
    RangeEx is start and end where end is exclusive
    RangeIn is start and end where end is inclusive

    start/end -> first/last
    (end seems too much like end() in stl)

3ef950abba Fixes for bigendian platforms
arch/alpha/vtophys.cc:
    PGOFSET -> ALPHA_PGOFSET to avoid include file problems
base/callback.hh:
    Added  a class to create a callback from a function
base/intmath.hh:
    make FloorLog2 inlined
dev/pcidev.cc:
    more work in getting pciconfig space happy with different endiannesses
dev/uart.cc:
    used an incorrect size for write uint64_t instead of uint8_t
sim/system.cc:
    when writing things into system data structures we need to pay
    attention to endianness

231fac0a2b more modifications for cross-endian support. linux now gets to pciconfig
dev/alpha_console.cc:
    rather than acessing a byte array for alpha access, access the members
    **this requires an updated console**
dev/pcidev.cc:
    correctly type all the pci data and store in in little endian no
    matter what system we are on
dev/tsunami_uart.cc:
    correct a bug with the data type.
kern/linux/linux_system.cc:
    system type in hwprb needs to be endian happy as well.

    to use PCI based MMU mappings only

    Properly setup the MMU after a serialize

    Removed StandardNumber and replaced with Number.
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
    LinuxSkipIdeDelay50msEvent was simply the same as the SkipFunc event,
    so I removed it. Same with with LinuxSkipFuncEvent.

ced021a78f Varied fixes to get linux running. Allow for shutdown on linux.
dev/ide_disk.cc:
    Fix to PIO writes and also add command needed for shutdown
dev/pcidev.cc:
    Change the panic on write to read-only registers to a debug print.  The
    kernel tries to write back over all of the PCI registers to restore
    the saved SRM state, so we need to let it do this without panicing.
sim/system.cc:
    Add back increment of number of running systems to allow trap of halt
    work correctly.

assumes that all PCI devices are DmaDevices, and if not, they can just
ignore the DMA stuff)
