[U-Boot] Missing SCSI block device connected to SATA adapter

[Kostya Porotchkin]

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
