Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.
IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)
This driver support mflash IO mode.
Followings are brief descriptions about IO mode.
1. IO mode based on ATA protocol and uses some custom command. (read
confirm, write confirm)
2. IO mode uses SRAM bus interface.

judging from other printfs in the same file, it seems ata should be
postpended with the interface number, not the address of the global
port variable. Fixes this for current u-boot-mpc83xx tree:
Configuring for MPC8349ITX board...

The code assumes that the pci bus address and the virtual
address used to access a region are the same, but they might
not be. Fix this assumption.

The driver need wait for the device updating signature to host.
If we don't wait for it, the driver can not detect the device(disk)
when the system powers up.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Add the Freescale on-chip SATA controller driver to u-boot,
The SATA controller is used on the 837x and 8315 targets,
The driver can be used to load kernel, fs and dtb.
The features list:
- 1.5/3 Gbps link speed
- LBA48, LBA28 support
- DMA and FPDMA support
- Two ports support

original ata_piix driver is using IDE framework, not real
SATA framework. For now, the ata_piix driver is only used
by x86 sc520_cdp board. This patch makes the ata_piix driver
use the new SATA framework, so
- remove the duplicated command stuff
- remove the CONFIG_CMD_IDE define in the sc520_cdp.h
- add the CONFIG_CMD_SATA define to sc520_cdp.h

move the cmd_sata.c from common/ to drivers/ata_piix.c,
the cmd_sata.c have some part of ata_piix controller drivers.
consolidate the driver to have better framework.
