6eef6eac1f dm: blk: Add a legacy block interface
There is quite a bit of duplicated common code related to block devices
in the IDE and SCSI implementations.

Create some helper functions that can be used to reduce the duplication.
These rely on a linker list of interface-type drivers

a219639d42 dm: Rename disk uclass to ahci
This started as 'ahci' and was renamed to 'disk' during code review. But it
seems that this is too generic. Now that we have a 'blk' uclass, we can use
that as the generic piece, and revert to ahci for this.

e40cf34a29 drivers: block: add block device cache
Add a block device cache to speed up repeated reads of block devices by
various filesystems.

This small amount of cache can dramatically speed up filesystem
operations by skipping repeated reads of common areas of a block
device (typically directory structures).

This has shown to have some benefit on FAT filesystem operations of
loading a kernel and RAM disk, but more dramatic benefits on ext4
filesystems when the kernel and/or RAM disk are spread across
multiple extent header structures as described in commit fc0fc50.

The cache is implemented through a minimal list (block_cache) maintained
in most-recently-used order and count of the current number of entries
(cache_count). It uses a maximum block count setting to prevent copies
of large block reads and an upper bound on the number of cached areas.

The maximum number of entries in the cache defaults to 32 and the maximum
number of blocks per cache entry has a default of 2, which has shown to
produce the best results on testing of ext4 and FAT filesystems.

The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows
changing these values and can be used to tune for a particular filesystem
layout.

169789dcb9 sata: Add SATA driver with DMA support for Marvell Kirkwood and Armada XP
This patch adds a new SATA driver for the Marvell Kirkwood and Armada
370 / XP SoC's.

This driver supports the SATA controller of some Mavell SoC's.
Here a (most likely incomplete) list of the supported SoC's:
- Kirkwood
- Armada 370
- Armada XP

This driver implementation is an alternative to the already available
driver via the "ide" commands interface (drivers/block/mvsata_ide.c).
But this driver only supports PIO mode and as this new driver also
supports transfer via DMA, its much faster.

Please note, that the newer SoC's (e.g. Armada 38x) are not supported
by this driver. As they have an AHCI compatible SATA controller
integrated.

The original version of this driver was sent by Tor Krill to the U-Boot
list a few years ago. Here the link:

http://lists.denx.de/pipermail/u-boot/2010-June/073147.html

Changes by Stefan:
- Coding-style cleanup
- Support for Armada XP added
- MBUS window setup added
- D-cache flush and invalidation added - works with dcache enabled on
  Armada XP
- Removed mdelay() from ata_wait_register() and add timer based timeout
  detection to speed up the transfer

e1783b5ba3 drivers: block: Remove the ata_piix driver
This driver was originally added to support the native IDE mode for
Intel chipset, however it has some bugs like not supporting ATAPI
devices, endianness issue, or even broken build when CONFIG_LAB48.
Given no board is using this driver as of today, rather than fixing
all these issues we just remove it from the source tree.

f4d8de48f5 sandbox: block driver using host file/device as backing store
Provide a way to use any host file or device as a block device in U-Boot.
This can be used to provide filesystem access within U-Boot to an ext2
image file on the host, for example.

The support is plumbed into the filesystem and partition interfaces.

We don't want to print a message in the driver every time we find a missing
device. Pass the information back to the caller where a message can be printed
if desired.

This patch add the u-boot driver (PIO) of ftide020 ATA (IDE) driver.
IDE commands include read, info, and other functions has been implemented.

Because this IDE controller support AHB interface only which is differ
from other most IDE controller supports PCI interface. Some registers
access is required during CMD/DATA I/O. Hence a configuration
"CONFIG_IDE_AHB" is required to be defined according to the feature in
cmd_ide.c.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

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.
