[U-Boot] [RFC 2/3] ata: sata_sil: Add sata DM support for Silicon driver
Peng Ma
peng.ma at nxp.com
Wed Sep 25 09:54:18 UTC 2019
This sata is a None AHCI sata device. It belongs to PCI sata. To support
DM mode with SCSI interface we use the SCSI_NONE_AHCI.
This patch is an example(pci sata) to fit "support SCSI interface for None AHCI sata"
