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

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

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

Currently, this driver uses a 28bit interface to AHCI, this
limits the number of blocks addressable to 2^28, or the max
disk size to 512(2^28) or about 137GB. This change allows
supporting drives up to about 2TB.
Testing this is a bit difficult. There is test code that
can be inserted into U-Boot that will write test patterns
into certain unused blocks. These patterns can be manually
checked using 'dd' after boot. Another way is to confirm the
original error that exposed this bug is fixed. IOW: see if
AU (Auto Update) will now work on the drive. Also, check
that there are no warning messages from the 'cgpt' utility.

Writes in u-boot are so rare, and the logic to know when is

usually, one extra flush when the rare writes do happen.

Note: These are timeout values and not delay values, so the event being
timed out will complete whenever it is actually ready, with a
measurement granularity of 1 millisecond, up till the timeout value.
Therefore, there is no effect on SSD booting.
The values were determined by instrumenting the code and measuring the
actual time taken by several different models of HDD for each of the
parameters and then adding 50% more for the spinup value and just
doubling the command timeout value.

Update the assignment of various physical memory buffers used by the
SATA controller to explicitly be denoted as physical addresses.
The memory is identity-mapped, so these function calls are a nop, but
they provide good semantic documentation for any maintainers.
The return value of virt_to_phys() is 'unsigned long'. On machines
where sizeof(unsigned long) != sizeof(pointer), a cast through
(uintptr_t) is needed to appease the compiler due to the potential of
losing the upper 32 bits of the address.
In compilation this scenario, a physical address could be 64-bits, yet
the C pointer environment only allows 32-bit addresses; the constraint
is that pointers cannot address more than 4Gb of memory and if
virt_to_phys() ever returns an out-of-range value for the physical
address, there are issues with emmory mapping which must be solved.
However, since the memory is identify mappeed, there is no problem
introducing the cast: the original pointer will reside in 32-bits, so
the physical address will also be within in 32-bits.

In the structure returned by the ATA identify device command, there are two
fields which describe the device capacity. One is a 32 bit data type which
reports the number of sectors as a 28 bit LBA, and the other is a 64 bit data
type which is for a 48 bit LBA. If the device doesn't support 48 bit LBAs,
the small value is the only value with the correct size. If it supports more,
if the number of sectors is small enough to fit into 28 bits, both fields
reflect the correct value. If it's too large, the smaller field has 28 bits of
1s, 0xfffffff, and the other field has the correct value.
The AHCI driver is implemented by attaching to the generic SCSI code and
translating on the fly between SCSI binary data structures and AHCI data
structures. It responds to requests to execute specific SCSI commands by
executing the equivalent AHCI commands and then crafting a response which
matches what a SCSI disk would send.
The AHCI driver now considers both fields and chooses the correct one when
implementing both the SCSI READ CAPACITY (10) and READ CAPACITY (16) commands.

This command doesn't really do anything when talking to a SATA device, and
sending it confuses some of them. This change makes sending the command
optional, and defaults to not. The situations where it should be sent are not
the common case.
With the standard SSD in the machine, here are some times with the option
turned off:
1. 8277
2. 8273
3. 8050
And turned on:
1. 8303
2. 8155
3. 8276
Sending that command seems to have no meaningful effect on performance.
This fixes problems with an SSD marked Toshiba NV6424, Taiwan 11159AE P

With an Intel AHCI controller, the driver does not operate properly
if the requested amount of blocks to read exceeds 255.
It is probably possible to specify 0 as the block count and the driver
will read 256 blocks, but it was decided to limit the number of blocks
read at once to 128 (it should be a power of 2 for the optimal
performance of solid state drives).

We set sata_curr_device to 0 right after returning from init_sata(), so there's
no point in setting it to the last scanned driver at this point.
Note: there are more duplicities with cmd_sata, but those might be required,
as the code seems to reset the entire controller on every scan, ignoring the
requested port number.

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.

IO mode is custom mode for the host that doesn't have IDE interface.
