This patch cleans ide/pci.c:
- useless casts
- split piix and cmd646 from pci.c, this allows remove some code
- clean cmd646 to allow th eremoval of pci_dev from BMDMAState.
Later, Juan.
Juan Quintela (12):
ide: change cast to DO_UPCAST
ide: Remove cast in pci_register_bar
ide: Remove duplicated definitions
ide: remove uselsess casts from void *
ide: create ide/pci.h for common ide pci definitions
ide: export needed ide-pci functions for split
ide: split cmd646 and piix from pci.c
ide: PCIIDEState type field is not needed anymore
ide: 'secondary' field is only used by cmd646
ide: cmd646 we can get the pci device with container_of
ide: cmd646 ->unit has just the value that we want
ide: BMDMAState don't need a pci_dev field anymore

This patch splits piix4 specific code from pci.c. And compile new piix.o and cmd646.o when they are needed. The only change that is not code movemet is removal of cmd646 specific parts in bmdma_readb/writeb for piix.
