-+ * IDE tuning and bus mastering support for the CS5510/CS5520
-+ * chipsets
-+ *
-+ * The CS5510/CS5520 are slightly unusual devices. Unlike the
-+ * typical IDE controllers they do bus mastering with the drive in
-+ * PIO mode and smarter silicon.
-+ *
-+ * The practical upshot of this is that we must always tune the
-+ * drive for the right PIO mode. We must also ignore all the blacklists
-+ * and the drive bus mastering DMA information. Also to confuse matters
-+ * further we can do DMA on PIO only drives.
-+ *
-+ * DMA on the 5510 also requires we disable_hlt() during DMA on early
-+ * revisions.

-+ *
-+ * The ITE8212 isn't exactly a standard IDE controller. It has two
-+ * modes. In pass through mode then it is an IDE controller. In its smart
-+ * mode its actually quite a capable hardware raid controller disguised
-+ * as an IDE controller. Smart mode only understands DMA read/write and
-+ * identify, none of the fancier commands apply. The IT8211 is identical
-+ * in other respects but lacks the raid mode.
-+ *
-+ * Errata:
-+ * o Rev 0x10 also requires master/slave hold the same DMA timings and
-+ * cannot do ATAPI MWDMA.
-+ * o The identify data for raid volumes lacks CHS info (technically ok)
-+ * but also fails to set the LBA28 and other bits. We fix these in
-+ * the IDE probe quirk code.
-+ * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
-+ * raid then the controller firmware dies
-+ * o Smart mode without RAID doesn't clear all the necessary identify
-+ * bits to reduce the command set to the one used
-+ *
-+ * This has a few impacts on the driver
-+ * - In pass through mode we do all the work you would expect
-+ * - In smart mode the clocking set up is done by the controller generally
-+ * but we must watch the other limits and filter.
-+ * - There are a few extra vendor commands that actually talk to the
-+ * controller but only work PIO with no IRQ.
-+ *
-+ * Vendor areas of the identify block in smart mode are used for the
-+ * timing and policy set up. Each HDD in raid mode also has a serial
-+ * block on the disk. The hardware extra commands are get/set chip status,
-+ * rebuild, get rebuild status.
-+ *
-+ * In Linux the driver supports pass through mode as if the device was
-+ * just another IDE controller. If the smart mode is running then
-+ * volumes are managed by the controller firmware and each IDE "disk"
-+ * is a raid volume. Even more cute - the controller can do automated
-+ * hotplug and rebuild.
-+ *
-+ * The pass through controller itself is a little demented. It has a
-+ * flaw that it has a single set of PIO/MWDMA timings per channel so
-+ * non UDMA devices restrict each others performance. It also has a
-+ * single clock source per channel so mixed UDMA100/133 performance
-+ * isn't perfect and we have to pick a clock. Thankfully none of this
-+ * matters in smart mode. ATAPI DMA is not currently supported.
-+ *
-+ * It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
-+ *
-+ * TODO
-+ * - ATAPI and other speed filtering
-+ * - Command filter in smart mode
-+ * - RAID configuration ioctls

-+ * pata_mpiix.c - Intel MPIIX PATA for new ATA layer
-+ * (C) 2005-2006 Red Hat Inc
-+ * Alan Cox <alan@redhat.com>
-+ *
-+ * The MPIIX is different enough to the PIIX4 and friends that we give it
-+ * a separate driver. The old ide/pci code handles this by just not tuning
-+ * MPIIX at all.
-+ *
-+ * The MPIIX also differs in another important way from the majority of PIIX
-+ * devices. The chip is a bridge (pardon the pun) between the old world of
-+ * ISA IDE and PCI IDE. Although the ATA timings are PCI configured the actual
-+ * IDE controller is not decoded in PCI space and the chip does not claim to
-+ * be IDE class PCI. This requires slightly non-standard probe logic compared
-+ * with PCI IDE and also that we do not disable the device when our driver is
-+ * unloaded (as it has many other functions).
-+ *
-+ * The driver conciously keeps this logic internally to avoid pushing quirky
-+ * PATA history into the clean libata layer.
-+ *
-+ * Thinkpad specific note: If you boot an MPIIX using thinkpad with a PCMCIA
-+ * hard disk present this driver will not detect it. This is not a bug. In this
-+ * configuration the secondary port of the MPIIX is disabled and the addresses
-+ * are decoded by the PCMCIA bridge and therefore are for a generic IDE driver
-+ * to operate.

-+ * VIA VT82C576 - MWDMA, 33Mhz
-+ * VIA VT82C586 - MWDMA, 33Mhz

-+ * Most registers remain compatible across chips. Others start reserved
-+ * and acquire sensible semantics if set to 1 (eg cable detect). A few

-+ *
-+ * One additional quirk of the VIA design is that like ALi they use few
