* scsi: dm: Unbind all scsi based block devices before new scanMichal Simek2017-01-09-0/+2
| | | | | | | | | | | | | | | | | | | | | | | New scan should unbind all block devices not to be listed again. Without this patch if scsi reset or scan is called new block devices are created which point to the same id and lun. For example: ZynqMP> scsi scan scsi_scan: if_type=2, devnum=0: sdhci@ff170000.blk, 6, 0 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 0 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 1 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 2 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 3 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 4 scanning bus for devices...

* dm: Add support for scsi/sata based devicesMichal Simek2016-12-20-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* dm: scsi: Separate the non-command code into its own fileSimon Glass2016-05-17-0/+567
At present the SCSI command code includes both the command-processing code and the core SCSI functions and data structures. Separate the latter into its own file, adding functions as needed to avoid the command code accessing data structures directly. This functions use the new legacy block functions. With this commit: - There is no CONFIG option referenced from the command code - The concept of a 'current SCSI device' is confined to the command code This will make it easier to convert this code to driver model.
