-Subject: [PATCH] libahci: Allow drivers to override stop_engine
-
-Marvell armada37xx, armada7k and armada8k share the same
-AHCI sata controller IP, and currently there is an issue
-(Errata Ref#226)that the SATA can not be detected via SATA
-Port-MultiPlayer(PMP). After debugging, the reason is
-found that the value of Port-x FIS-based Switching Control
-(PxFBS@0x40) became wrong.
-According to design, the bits[11:8, 0] of register PxFBS
-are cleared when Port Command and Status (0x18) bit[0]
-changes its value from 1 to 0, i.e. falling edge of Port
-Command and Status bit[0] sends PULSE that resets PxFBS
-bits[11:8; 0].
-So it needs save the port PxFBS register before PxCMD
-ST write and restore the port PxFBS register afterwards
-in ahci_stop_engine().
-
-This commit allows drivers to override ahci_stop_engine
-behavior for use by the Marvell AHCI driver(and potentially
-other drivers in the future).

-Subject: [PATCH] ata: ahci: mvebu: override ahci_stop_engine for mvebu AHCI
-
-There is an issue(Errata Ref#226) that the SATA can not be
-detected via SATA Port-MultiPlayer(PMP) with following
-error log:
-  ata1.15: PMP product ID mismatch
-  ata1.15: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
-  ata1.15: Port Multiplier vendor mismatch '0x1b4b'!='0x0'
-  ata1.15: PMP revalidation failed (errno=-19)
-
-After debugging, the reason is found that the value Port-x
-FIS-based Switching Control(PxFBS@0x40) become wrong.
-According to design, the bits[11:8, 0] of register PxFBS
-are cleared when Port Command and Status (0x18) bit[0]
-changes its value from 1 to 0, i.e. falling edge of Port
-Command and Status bit[0] sends PULSE that resets PxFBS
-bits[11:8; 0].
-So it needs a mvebu SATA WA to save the port PxFBS register
-before PxCMD ST write and restore it afterwards.
-
-This patch implements the WA in a separate function of
-ahci_mvebu_stop_engine to override ahci_stop_gngine.
