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.

f3a7930fa6 Fixes to IDE disk to fix serialization. Now passes simple CPU serialize
tests

dev/ide_ctrl.cc:
    Formatting
dev/ide_disk.cc:
    Remove some junk, add an assert to serialize, and add missing serialize
    for command register.

bfcb088281 minor mods for mimicking NS83820 functionality
dev/ide_ctrl.cc:
    generalize these #defs
dev/ide_ctrl.hh:
    put these in pcireg.h
dev/ns_gige.cc:
    do i need io_enable?  and assert will fail if i actually need to implement it, which may give clue as to wehtehr i need to implmeent the mem_enable and bm_enable stuff.
dev/ns_gige.hh:
    implement this in case it's needed
dev/pcireg.h:
    put these defs in pcireg instead

ca0dcd048c after unserialization in the ide driver we need to reprogram the
busbridges. Also small fix for gcc 3.3.3.

dev/etherpkt.hh:
    Gcc 3.3.3 wants assert.h to be include in this file.
dev/ide_ctrl.cc:
    after unserialization we need to tell the busbridges what addresses to
    respond to.

02f69b94c5 Fixes for detailed boot, made cttz and ctlz instructions more compact,
and started cleaning up config files.

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.

    the MMU
dev/ns_gige.cc:
dev/ns_gige.hh:
    Remove the "addr" paramter from the constructor and change the device
    to use PCI based MMU mappings only

f5c7b1358c Remove the uncacheable bit 39 check (needs to be merged in with head tree
if Tru64 is to continue to be supported on Turbolaser) and fixed
translation of physical addresses by clearing PA<42:35> when the real
uncachable bit (43) is set

arch/alpha/ev5.hh:
    Change to support 256 ASNs and seperate VA_SPACE checks for EV5 and EV6
    also add support proper translation of uncacheable physical addresses
dev/ide_ctrl.cc:
    Fix to work with real address translation

future: see note below.

dev/tsunamireg.h:
    Added ULL for 64bit ints
kern/linux/linux_system.cc:
    Added a function to skip determine_cpu_caches, right now it is only used for
    printing in proc, however in the future we may either want to implement the SC_CTL
    IPR register or manually set alpha_l1i_cacheshape, alpha_l1d_cacheshape,
    alpha_l2_cacheshape, alpha_l3_cacheshape to ((size << 10) | (linesize>>1)<<4 | way)
kern/linux/linux_system.hh:
    added event to skip determine_cpu_caches()

6807c319b0 Checkin of latest IDE and some separation between platforms (Tsunami and
Turbolaser)

base/range.hh:
    Change semantics of range to be inclusive of the end value, may need to
    check other users of range to make sure they are semantically correct.
    This was needed for access of last byte in range of address on IDE and
    makes sense for case of range from 0 to all f
