| | | | | | | | | | | | | | | | | | | | | | | | | | | | Data transfers are not required to be block aligned in memory, so they span two pages. Fix this by splitting the call to >sff_data_xfer into two for that case. This has been broken since the initial libata import before the damn of git, but was uncovered by the legacy ide driver removal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to create a proper PCI driver for the IXP4xx we need to make the old PCI driver and its reliance on <mach/io.h> optional. Create a new Kconfig symbol for the legacy PCI driver IXP4XX_PCI_LEGACY and only activate NEED_MACH_IO_H for this driver. A few files need to be adjusted to explicitly include the <mach/hardware.h> and <mach/cpu.h> headers that they previously obtained implicitly using <linux/io.h> that would include <mach/io.h> and in turn include these two headers. This breaks our reliance on the old PCI and indirect PCI support so we can reimplement a proper purely DT-based driver in the PCI subsystem.

| * | scsi: core: Drop obsolete Linux-specific SCSI status codesHannes Reinecke2021-06-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally the SCSI subsystem has been using 'special' SCSI status codes, which were the SAM-specified ones but shifted by 1. As most drivers have now been modified to use the SAM-specified ones, having two nearly identical sets of definitions only causes confusion. The Linux-specifed SCSI status codes have been marked obsolete for several years so drop them and use the SAM-specified status codes throughout.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

* | m68k/q40: Replace q40ide driver with pata_falcon and falconideFinn Thain2021-06-112-20/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows m68k q40 systems to switch from the deprecated IDE subsystem to libata. Enhance the byte-swapping falconide and pata_falcon platform drivers to accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem to co-exist with q40 IRQ arrangements without too much mess. The new IO resources were added solely for the purpose of making request_region() reservations identical to those made by q40ide: these regions aren't used for actual IO.

By default all enabled locations are tried, however it may interfere with a different kind of hardware responding there. For example with a plain (E)ISA system the driver tries all the six possible locations: scsi host0: pata_legacy ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100 ata1.00: 19541088 sectors, multi 16: LBA ata1.00: configured for PIO scsi 0:0:0:0: Direct-Access ATA ST310211A 3.54 PQ: 0 ANSI: 5 scsi 0:0:0:0: Attached scsi generic sg0 type 0 sd 0:0:0:0: [sda] 19541088 512-byte logical blocks: (10.0 GB/9.32 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk scsi host1: pata_legacy ata2: PATA max PIO4 cmd 0x170 ctl 0x376 irq 15 scsi host1: pata_legacy ata3: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11 scsi host1: pata_legacy ata4: PATA max PIO4 cmd 0x168 ctl 0x36e irq 10 scsi host1: pata_legacy ata5: PATA max PIO4 cmd 0x1e0 ctl 0x3e6 irq 8 scsi host1: pata_legacy ata6: PATA max PIO4 cmd 0x160 ctl 0x366 irq 12 however giving the kernel "pata_legacy.probe_mask=21" makes it try every other location only: scsi host0: pata_legacy ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100 ata1.00: 19541088 sectors, multi 16: LBA ata1.00: configured for PIO scsi 0:0:0:0: Direct-Access ATA ST310211A 3.54 PQ: 0 ANSI: 5 scsi 0:0:0:0: Attached scsi generic sg0 type 0 sd 0:0:0:0: [sda] 19541088 512-byte logical blocks: (10.0 GB/9.32 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk scsi host1: pata_legacy ata2: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11 scsi host1: pata_legacy ata3: PATA max PIO4 cmd 0x1e0 ctl 0x3e6 irq 8 Signed-off-by: Maciej W.

Also several comments are inaccurate or wrong. Add the missing documentation pieces then and reorder parameters into a consistent block. Remove inaccuracies as follows: - `all' affects primary and secondary port ranges only rather than all, - `probe_all' affects tertiary and further port ranges rather than all, - `ht6560b' is for HT 6560B rather than HT 6560A.

In some scenarios, some ports are not external SATA ports, and it cause disks connected to these ports to be identified as removable disks. So disable the SXS capability on the software side to prevent users from mistakenly considering non-removable disks as removable disks and performing related operations.
