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.

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.

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

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

This patch changes the initialization of the AHCI controller to not
enable the default interrupts (DEF_PORT_IRQ). As interrupts are
not used in U-Boot in general, this should not break the common AHCI
driver operation.
This change is needed to support the Marvell Armada 38x AHCI
controller. With interrupts enabled, this results in timeouts in
ahci_device_data_io(). Not enabling these interrupts fixes this
problem and the common AHCI driver works fine.

In stead of user_buffer_size, transfer_size should be used to pass to
ahci_device_data_io(). transfer_size is the length that we want the
low level function to transfer each time.
If we use user_buffer_size which is the totally data length as parameter,
low level function will actually create many SGs to transfer as many data
as possible each time. That will produce many redundant data transfer.

Each time U-Boot boots on Intel Crown Bay board, the displayed hard
drive information is wrong. It could be either wrong capacity or just
a 'Capacity: not available' message. After enabling the debug switch,
we can see the scsi inquiry command did not execute successfully.
However, doing a 'scsi scan' in the U-Boot shell does not expose
this issue.

So uninitialized contents on the stack were passed to dev_print() to

The symptom were observed on two hard drives (one is Seagate, the

from task file register after enabling the port in ahci_port_start()
before proceeding other operations like scsi_scan().

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done
for sun7i only since I don't have access to any other sunxi platforms
with sata included.
The PHY setup is derived from the Alwinner releases and Linux, but is mostly
undocumented.
The Allwinner AHCI controller also requires some magic (and, again,
undocumented) DMA initialisation when starting a port. This is added under a
suitable ifdef.
This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on
contents of Linux DTS files, including SATA power pin config taken from the
DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.
