2008-05-19sata_mv: ensure empty request queue for FBS-NCQ EHMark Lord
Check for an empty request queue before stopping EDMA after a FBS-NCQ error, as per recommendation from the Marvell datasheet. This ensures that the EDMA won't suddenly become active again just after our subsequent check of the empty/idle bits. Also bump DRV_VERSION.

2008-05-19sata_mv: cache main_irq_mask register in hprivMark Lord
Part five of simplifying/fixing handling of the main_irq_mask register to resolve unexpected interrupt issues observed in 2.6.26-rc*. Keep a cached copy of the main_irq_mask so that we don't have to stall the CPU to read it on every pass through mv_interrupt. This significantly speeds up interrupt handling, both for sata_mv, and for any other driver/device sharing the same PCI IRQ line.

2008-05-19sata_mv: disregard masked irqsMark Lord
Part four of simplifying/fixing handling of the main_irq_mask register to resolve unexpected interrupt issues observed in 2.6.26-rc*. Ignore masked IRQs in mv_interrupt(). This prevents "unexpected device interrupt while idle" messages. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-19sata_mv: fix pmp drives not foundMark Lord
Part three of simplifying/fixing handling of the main_irq_mask register to resolve unexpected interrupt issues observed in 2.6.26-rc*. Partially fix a reported bug whereby we sometimes miss seeing drives on a port-multiplier, as reported by Gwendal Grignou <gwendal@google.com>. The problem was that we were receiving unexpected interrupts during EH from POLLed commands while accessing port-multiplier registers. These unexpected interrupts can be prevented by masking the DONE_IRQ bit for the port whenever not operating in EDMA mode. Also fix port_stop() to mask all port interrupts.

2008-05-19sata_mv: consolidate main_irq_mask updatesMark Lord
Part two of simplifying/fixing handling of the main_irq_mask register to resolve unexpected interrupt issues observed in 2.6.26-rc*. Consolidate all updates of the host main_irq_mask register into a single function. This simplifies maintenance, and also prepares the way for caching it (later). No functionality changes in this update. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-19sata_mv: don't blindly enable IRQsMark Lord
Part one of simplifying/fixing handling of the main_irq_mask register to resolve unexpected interrupt issues observed in 2.6.26-rc*. Don't blindly enable port IRQs at host init time. Instead, enable only the bits that we want, which in this case is simply the PCI_ERR bit. The per-port bits can wait until the ports are reset/probed for devices.

2008-05-19sata_mv: async notify for genIIe onlyMark Lord
Now that we handle the FIS_IRQ_CAUSE register correctly, we can also now handle SATA asynchronous notification events. So enable them, but only for the more modern GenIIe chips. (older chips have unaddressed errata issues related to this). This fixes hot plug/unplug for port-muliplier ports.

2008-05-19sata_mv: group genIIe flagsMark Lord
Group all of the flags for GenIIe devices into a common definition, to ensure that any updates to them are shared by all GenIIe devices. This will help make future maintenance somewhat simpler. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-19sata_mv: fis irq register fixesMark Lord
Fix handling of the FIS_IRQ_CAUSE register in sata_mv. This register exists *only* on GenIIe devices, so don't bother writing to it on older chips. Also, it has to be read/cleared in mv_err_intr() before clearing the main ERR_IRQ_CAUSE register. This keeps sata_mv from getting stuck forever on certain error types.

2008-05-19pata-bf54x: Set ATAPI HSM to control IDE device terminate sequence.Sonic Zhang
Set ATAPI host state machine to control IDE device terminate sequence. Some IDE harddisk may assert terminate sequence in the middle of a formal DMA transaction and resume later. Bit DETECT_TERM in ATAPI_CTRL register determines whether the ATAPI host state machine or the kernel driver should take care of this case.
