  • c4d660d4d   dm: mmc: Allow disabling driver model in SPL ... Browse Code »

    At present if U-Boot proper uses driver model for MMC, then SPL has to
    also. While this is desirable, it places a significant barrier to moving
    to driver model in some cases. For example, with a space-constrained SPL
    it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
    adjusting some drivers.

    Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By
    default these follow their non-SPL versions, but this can be changed by
    boards which need it.

  • e8a016b53   dm: Add support for scsi/sata based devices ... Browse Code »

    All sata based drivers are bind and corresponding block
    device is created. Based on this find_scsi_device() is able
    to get back block device based on scsi_curr_dev pointer.

    intr_scsi() is commented now but it can be replaced by calling
    find_scsi_device() and scsi_scan().

    scsi_dev_desc[] is commented out but common/scsi.c heavily depends on
    it. That's why CONFIG_SYS_SCSI_MAX_DEVICE is hardcoded to 1 and symbol
    is reassigned to a block description allocated by uclass.
    There is only one block description by device now but it doesn't need to
    be correct when more devices are present.

    scsi_bind() ensures corresponding block device creation.
    uclass post_probe (scsi_post_probe()) is doing low level init.

    SCSI/SATA DM based drivers requires to have 64bit base address as
    the first entry in platform data structure to setup mmio_base.

  • e40cf34a2   drivers: block: add block device cache ... Browse Code »

    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.

  • 169789dcb   sata: Add SATA driver with DMA support for Marvell Kirkwood and Armada XP ... Browse Code »

    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

    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.

  • 6d8962e81   Switch from archive libraries to partial linking ... Browse Code »

    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.
    (Many mobile targeted SoC doesn't have IDE bus)

    This driver support mflash IO mode.

    Followings are brief descriptions about IO mode.

    1. IO mode based on ATA protocol and uses some custom command. (read
    confirm, write confirm)
    2. IO mode uses SRAM bus interface.
