drivers: block: add block device cache

2016-04-01T21:18:27+00:00

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.

dm: blk: Add a block-device uclass

2016-03-14T21:34:50+00:00

Add a uclass for block devices. These provide block-oriented data access,
supporting reading, writing and erasing of whole blocks.

ahci: Add a disk-controller uclass

2016-01-24T04:09:39+00:00

Add a uclass ID for a disk controller. This can be used by AHCI/SATA or
other controller types. There are no operations and no interface so far,
but it is possible to probe a SATA device.

sata: Add SATA driver with DMA support for Marvell Kirkwood and Armada XP

2016-01-14T13:08:59+00:00

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

drivers: block: Remove the ata_piix driver

2015-07-15T00:03:20+00:00

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.

sandbox: block driver using host file/device as backing store

2014-01-09T00:24:03+00:00

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.
