    dm: Add support for scsi/sata based devices · e8a016b5
    Michal Simek authored
    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.
