Andrew Schultz 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
dev/ide_ctrl.cc:
dev/ide_ctrl.hh:
dev/ide_disk.cc:
