Currently Freescale QorIQ series SATA is supported by ahci_platform
driver. Some SoC specific settings have been put in uboot. So whether
SATA works or not heavily depends on uboot.
This patch will add a new driver to support QorIQ sata which removes
the dependency on any other boot loader.
Freescale QorIQ series sata, like ls1021a ls2085a ls1043a, is
compatible with serial ATA 3.0 and AHCI 1.3 specification.

This patch adds ACPI supports for AHCI platform driver, which uses _CLS
method to match the device.
The following is an example of ASL structure in DSDT for a SATA controller,
which contains _CLS package to be matched by the ahci_platform driver:
Device (AHC0) // AHCI Controller
{
Name(_HID, "AMDI0600")
Name (_CCA, 1)
Name (_CLS, Package (3)
{
0x01, // Base Class: Mass Storage
0x06, // Sub-Class: serial ATA
0x01, // Interface: AHCI
})
Name (_CRS, ResourceTemplate ()
{
Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000)
Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
})
}
Also, since ATA driver should not require PCI support for ATA_ACPI,
this patch removes dependency in the driver/ata/Kconfig.

then disabled for ARM and ARM64 by commit 2de5a9c004 ("sata_dwc_460ex:

broken.
This disabled is entirely, because it's too noisy on x86-64 too, and
there's no point in disabling architectures one by one. At a minimum,
the code isn't 64-bit clean, and even on 32-bit it is questionable

AHCI_XGENE is only applicable on ARM64 but it can also be enabled for
compile testing; however, AHCI_XGENE selects PHY_XGENE which has other
arch specific dependencies. This leads to the following warning when
enabling it on other archs for compile testing.
warning: (AHCI_XGENE) selects PHY_XGENE which has unmet direct
dependencies (HAS_IOMEM && OF && (ARM64 || COMPILE_TEST))
Selecting a config option which itself has dependencies can easily
lead to broken configurations. For now, let's just make AHCI_XGENE

the HBA registers, the Vendor Specific registers, the AHCI PHY clock
and the AHCI signals adjustment window(GPR13 register).
- CAP_SSS(bit20) of the HOST_CAP is writable, default value is '0',
should be configured to be '1'
- bit0 (only one AHCI SATA port on imx6q) of the HOST_PORTS_IMPL

- One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be

- Remove a workaround from kernel/irq/irqdomain.c which was there
exclusivly for MIPS. Patch by Grant Likely.
- More small improvments for the SEAD 3 platform
- Improvments on the BMIPS / SMP support for the BCM63xx series.
- Various cleanups of dead leftovers.
- Platform support for the Cavium Octeon-based EdgeRouter Lite.
Two large KVM patchsets didn't make it for this pull request because
their respective authors are vacationing"

MIPS: APSP: Remove <asm/kspd.h>
SSB: Kconfig: Amend SSB_EMBEDDED dependencies
MIPS: microMIPS: Fix improper definition of ISA exception bit.

The motivation for this is to allow the driver to be
used with the r8a7790 SoC.
I believe that rather than adding another SoC to the list of allowed SoCs
it is better to simply remove the dependency of the driver on shmobile all
together.

ODD is not a common TLA for non-ATA people so they will get confused
by its meaning when they are configuring the kernel. This patch fixed
this problem by using ODD only after stating what it is.

Discussion was continuing after patch application, trying to figure out how
to best mesh exported data with the installers, boot-time agents and other
parties that want this info.
2) Merge Zero-Power Optical Device Driver (ZPODD) support, bringing
the wonderfulness of sane power management to your CD/DVD device.
Includes one SCSI-subsystem patch (with appropriate ACKs),
adding runtime PM support to 'sr' driver. That is the ZPODD interaction
bits.
Patchset went through some 13 revisions before it got here; kudos to
Intel for persistence.
3) pata_samsung_cf: use devm_clk_get()
4) more ata_piix, ahci PCI IDs
5) Add SATA driver for R-Car SoC
6) Convert libata to use devm_ioremap_resource (Note: I think
Greg sent this to you, also)
7) Set proper Sense Key (SK) in the SCSI simulator when
ATA passthrough indicates check condition. Google and specification
hawks everywhere shall rejoice.

Pull s390 update from Martin Schwidefsky:
"The most prominent change in this patch set is the software dirty bit
patch for s390. It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
the page_test_and_clear_dirty primitive which makes the common memory
management code a bit less obscure.
Heiko fixed most of the PCI related fallout, more often than not
missing GENERIC_HARDIRQS dependencies. Notable is one of the 3270
patches which adds an export to tty_io to be able to resize a tty.
The rest is the usual bunch of cleanups and bug fixes."
