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.
