4408f6f445 dm: blk: Fix get_desc to return block device descriptor
Current get_desc() implementation is not able to succesfully
finish and return pointer to block device descriptor.

Also function always return non zero value even device is found.

The patch fills block device descriptor and return 0 if device is found.

22f5de6b5c ahci: Make ahci_port_base() non-static to enable overwrite
To allow a board- / platform-specific ahci_port_base() function, this
patch removes "static inline" and adds __weak to this function. This
will be used by the upcoming Armada 7K/8K SATA / AHCI support, which
unfortunately needs a different port base address calculation.

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.

81e33f4b65 arm: mvebu: Move SoC selection (A38X vs AXP) into Kconfig
Until now, the SoC selection for the ARCH_MVEBU platforms has been done
in the config header. Using CONFIG_ARMADA_XP in a non-clear way. As
it needed to get selected for AXP and A38x based boards. This patch
now changes this to move the SoC selection to Kconfig. And also
uses CONFIG_ARCH_MVEBU as a common define for both AXP and A38x.
This makes things a bit clearer - especially for new board additions.

Additionally the defines CONFIG_SYS_MVEBU_DDR_AXP and
CONFIG_SYS_MVEBU_DDR_A38X are replaced with the already available
CONFIG_ARMADA_38X and CONFIG_ARMADA_XP.

And CONFIG_DDR3 is removed, as its not referenced anywhere.

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
