SConscript:
compile ide devices
base/chunk_generator.hh:
add another parameter to the chuck generator called complete() which
returns the number of bytes transfered so far. Very useful for
adding to a pointer.
configs/test/fs.py:
Add ide disk to fs test configuration

dev/ide_ctrl.hh:
dev/ide_disk.cc:
dev/ide_disk.hh:
dev/io_device.cc:
dev/io_device.hh:
dev/pciconfigall.cc:
dev/pciconfigall.hh:
dev/pcidev.cc:
dev/pcidev.hh:
update for new memory system
mem/bus.cc:
support devices that return multiple ranges
remove old ranges before using new info
mem/packet.hh:
make senderstate void* per steve's request that we use every
construct possible in C++
mem/physical.cc:
have memory stamp the packet with the time.
mem/physical.hh:
actually set the memory latency variable
python/m5/objects/Device.py:
Add DmaDevice
python/m5/objects/Ide.py:
Ide disk no longer has a physmem pointer
python/m5/objects/Pci.py:
update pci device for newmem
python/m5/objects/PhysicalMemory.py:
add latency parameter for physical memory
sim/byteswap.hh:
use fast architecture dependent byteswap calls if they exist
