ata: Add i.MX AHCI driver ...

This adds the glue code for the i.MX SATA controller. This controller
needs some i.MX specific setup and some SoC specific setting outside
the controller itself. The code for setting up the correct clock source
for the SATA phy has been taken from U-Boot.

ata: Add ahci support ...

This adds ahci controller support based on U-Boot ahci support. Unlike
U-Boot we do not push the SCSI layer in between, but use the ata interface
directly. Tested on a Freescale i.MX53.

ata: split ide sff suport to separate file ...

Currently we only support oldschool IDE SFF devices. This is done
by registering a register layout struct and everything else is done
by the generic IDE SFF driver. Since modern ATA devices still use
ATA, but not the SFF interface anymore, split out the IDE SFF support
to a separate file to allow for other types of ata interfaces.

ata: Add i.MX PATA driver support ...

Straight forward driver, we only have to configure some additional
bits and then use the generic ide support.

Add driver for IDE like interfaces ...

This simple driver enables a generic driver for ATA type of devices to get
access to the so called 'register file' of an ATA drive.

ATA/DISK: The BIOS based disk driver is not an interface ...

Using the BIOS to access attached hard disks means a full disk driver, not only
an interface to the drives.

ATA/DISK: Reorganize file structure and names for future updates ...

'ATA' means more an interface than a disk drive. Change the names to reflect
their real meaning.

Add a low level disk drive access driver ...

This is a low level disk drive communication driver. It uses the real mode
BIOS found on most x86 platforms, to read and write sectors. Used by the
generic disk driver.

Add the main disk driver ...

This is the generic disk driver. It does not know how to access the drives.
Other low level drivers are required for this.
