[U-Boot] [v2 1/2] ata: fsl_sata: Add DM support for Freescale PowerPC SATA driver
Peng Ma
peng.ma at nxp.com
Wed Oct 23 10:56:46 UTC 2019
Add DM support for Freescale PowerPC sata driver used for PowerPC T series SoCs,
CONFIG_BLK needs to be enabled on these platforms. It adds the SATA controller as
AHCI device, which is strictly speaking not correct, as the controller is not AHCI
compatible, But the U-Boot AHCI uclass interface enables the usage of this DM driver,
Also fix below warning while PowerPC T series boards compilation,
===================== WARNING ======================"
This board does use CONFIG_LIBATA but has CONFIG_AHCI not"
enabled. Please update the storage controller driver to use"
CONFIG_AHCI before the v2019.07 release."
Failure to update by the deadline may result in board removal."
See doc/driver-model/MIGRATION.txt for more info."
===================================================="

Changed for v2:
- Rewrite the subject and description
- Copy lba48 for new block device
