Currently this driver only works with a DesignWare DMA engine which it
registers manually using the second "reg" address range and interrupt
number from the DT node.

This patch makes the driver instead use the "dmas" property if present,
otherwise optionally falling back on the old way so existing device
trees can continue to work.

With this change, there is no longer any reason to depend on the 460EX
machine type so drop that from Kconfig.

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.

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.

Commit 84683a7e ("sata_dwc_460ex: enable COMPILE_TEST for the

then disabled for ARM and ARM64 by commit 2de5a9c0 ("sata_dwc_460ex:
disable compilation on ARM and ARM64") because it's too noisy and
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
whether it makes sense.

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
depend on PHY_XGENE which has all the necessary dependencies already.
