2016-10-11dm: blk: Enable CONFIG_BLK if DM_MMC is enabledSimon Glass

2016-09-27ahci: Make ahci_port_base() non-static to enable overwriteStefan Roese
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.

2016-05-17dm: Rename disk uclass to ahciSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17Revert "dm: sandbox: Drop the pre-DM host implementation"Simon Glass
Bring this support back so that sandbox can be compiled with CONFIG_BLK. This allows sandbox to have greater build coverage during the block-device transition. This can be removed again later.

2016-04-01drivers: block: add block device cacheEric Nelson
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. Signed-off-by: Eric Nelson <eric@nelint.com>

2016-01-14arm: mvebu: Move SoC selection (A38X vs AXP) into KconfigStefan Roese
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. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
2016-01-14sata: Add SATA driver with DMA support for Marvell Kirkwood and Armada XPTor Krill
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 Signed-off-by: Tor Krill <tor@excito.com> Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr> Cc: Tom Rini <trini@konsulko.com>

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.
