  • 681357ffd   dm: ahci: Add a driver for SCSI on AHCI ... Browse Code »

    Some AHCI drivers use SCSI under the hood. Rather than making the AHCI
    driver be in the SCSI uclass it makes sense to have the AHCI device create
    a SCSI device as a child. That way we can handle any AHCI-specific
    operations rather than trying to pretend tha the device is just SCSI.

    To handle this we need to provide a way for AHCI drivers to bind a SCSI
    device as its child, and probe it. Add functions for this.

  • 4279efc4c   dm: ahci: Drop use of probe_ent ... Browse Code »

    With driver model we cannot have static data or assume that there is only
    one device of each time. Adjust the code so that 'probe_ent' is not needed
    with driver model. Add a new ahci_init_dm() function which can init AHCI
    for driver model without re-allocating the uclass data. Move over the only
    existing driver to use this new function.

    Two AHCI drivers use SCSI with CONFIG_DM_SCSI. The SCSI uclass calls
    scsi_low_level_init() which is implemented by ahci.c. If
    CONFIG_SCSI_AHCI_PLAT is defined it does one thing and if it is not
    it does something else.

    We don't need to call through scsi_low_level_init() to get the init
    completed. Instead, adjust the two drivers to call into AHCI directly.
    Drop the post-probe init in the SCSI uclass. This means that driver model
    doesn't need to use scsi_low_level_init(). It is a legacy function and
    driver model should use a driver's probe() method instead.

    While we are here, add a comment to the top of the file explaining what
    ahci.c does.

    This array relates to the AHCI controller so should be exist out on its
    own in the file. Move it into the structure. Adjust functions that need
    access to this to take the structure as a parameter.

  • 2c9f9efb3   dm: ahci: Rename struct ahci_probe_ent ... Browse Code »

    This is not a very useful name since once it is probed it still hangs
    around. With driver model we will use uclass data for this, so rename the
    struct.

  • 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.

  • a6e50a88d   ahci: provide sunxi SATA driver using AHCI platform framework ... Browse Code »

    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.

    Especially, all sequences of SPACEs followed by TAB characters get

    Also remove all embedded "vim:" and "vi:" statements which hide
