Revision 242ce41fc92214c3430495edd43783c3ba3dcd2b authored by Sergei Shtylyov on 30 December 2006, 00:49:18 UTC, committed by Linus Torvalds on 30 December 2006, 18:56:43 UTC
There's no need to check in piix_config_drive_for_dma() for broken MW DMA mode 0 as this mode is not supported by the driver (it sets hwif->mwdma_mask to 0x6), and hence can't be selected by ide_dma_speed(). (Alan sayeth "Probably right but if not you've got a subtle corruptor. Should at least stick a BUG_ON mode 0 setting right close when the mode is set.")

*
* To put things into perspective, consider sparc64 with a few PCI controllers.
* Each type would have an own structure, with instances related one to one.
* We have only pcic on sparc, but we want to be compatible with sparc64 pbm.h.
* All three represent different abstractions.
* pci_bus - Linux PCI subsystem view of a PCI bus (including bridged buses)
* pbm - Arch-specific view of a PCI bus (sparc or sparc64)
* pcic - Chip-specific information for PCIC.
