The SCC PATA interface is only used by celleb.
celleb has been dropped [1], so drop the drivers.

The Marvell Armada 380 SoC includes two AHCI compatible
interfaces. However, like all DMA-capable Marvell interface, they
require special handling to configure MBus windows. Therefore, this
commit adds a new ahci_mvebu driver, which relies on the
libahci_platform.c code recently introduced.

Add the new ahci_da850 host driver.

Platform changes needed to make DaVinci DA850 SATA AHCI support
fully functional are in the separate "ARM: davinci: da850: update
SATA AHCI support" commit.

Please note that this driver doesn't have the superfluous clock
control code as clock is already handled by the generic AHCI
platform library code.

This patch adds support for the ahci sata controler found on Allwinner A10
and A20 SoCs to the ahci_platform driver.

Orignally written by Olliver Schinagl using the approach of having a platform
device which probe method creates a new child platform device which gets
driven by ahci_platform.c, as done by ahci_imx.c .

Refactored by Hans de Goede to add most of the non sunxi specific functionality
to ahci_platform.c and use a platform_data pointer from of_device_id for the
sunxi specific bits.

imx6q contains one Synopsys AHCI SATA controller, But it can't share
ahci_platform driver with other controllers because there are some
misalignments of the generic AHCI controller - the bits definitions of
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
   should be set to be '1'.(default 0)

 - One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be
   configured regarding to the frequency of AHB bus clock.

 - Configurations of the AHCI PHY clock, and the signal parameters of
   the GPR13

Setup its own ahci sata driver, contained the imx6q specific
initialized codes, re-use the generic ahci_platform driver, and keep
the generic ahci_platform driver clean as much as possible.

The ODD can be enabled for ZPODD if the following three conditions are
satisfied:
1 The ODD supports device attention;
2 The platform can runtime power off the ODD through ACPI;
3 The ODD is either slot type or drawer type.
For such ODDs, zpodd_init is called and a new structure is allocated for
it to store ZPODD related stuffs.

And the zpodd_dev_enabled function is used to test if ZPODD is currently
enabled for this ODD.

A new config CONFIG_SATA_ZPODD is added to selectively build ZPODD code.

Calxeda highbank SATA phy has intermittent problems bringing up a link

but each reset also disables spread spectrum support. The reset function
also needs to reprogram the phy to enable spread spectrum support.

  - use dev_get_drvdata
v3:
  - add missing clk_put() calls
  - use platform_get_irq()
  - fix resume code to avoid disabling IORDY on resume

Make BMDMA optional depending on new config variable CONFIG_ATA_BMDMA.
In Kconfig, drivers are grouped into five groups - non-SFF native, SFF
w/ custom DMA interface, SFF w/ BMDMA, PIO-only SFF, and generic
fallback / legacy ones.  Kconfig and Makefile are reorganized
according to the groups and ordered alphabetically inside each group.

ata_ioports.bmdma_addr and ata_port.bmdma_prd[_dma] are put into
CONFIG_ATA_BMDMA, as are all bmdma related ops, variables and
functions.

This increase the binary size slightly when BMDMA is enabled but on
both native-only and PIO-only configurations the size is slightly
reduced.  Either way, the size difference is insignificant.  This
change is more meaningful to signify the separation between SFF and
BMDMA and as a tool to verify the separation.

This is a libata driver for the "macio" IDE controller used on most Apple
PowerMac and PowerBooks. It's a libata equivalent of drivers/ide/ppc/pmac.c

It supports all the features of its predecessor, including mediabay hotplug

The timing calculations have been simplified to use pre-calculated tables
compared to drivers/ide/pmac.c and it uses the new mediabay interface
provided by a previous patch.

Make PMP support optional by adding CONFIG_SATA_PMP and leaving out
