Hi Konstantin, + Ken
your colleague contacted me privately regarding similar stuff and he has DM based driver. I think you should get in touch together to discuss this.
Thanks, Michal

Hello,
I am trying to use the new SCSI code with CONFIG_BLK=y on a Marvell board. I added CONFIG_DM_SCSI=y to my default configuration too. However "scsi reset" does not detect the connected hard disk since the execution flow never entered the "uclass_foreach_dev" loop in scsi_scan() function. My device is "UCLASS_AHCI" (arch/arm/mach-mvebu/sata.c) and calls ahci_init(). Should I take any additional steps for being registered as a SCSI device too?
Thank you for help! Konstantin
