From fa89f53bd7288d6aa7a982841119e7123faf5a53 Mon Sep 17 00:00:00 2001
From: Evan Wang <xswang@marvell.com>
Date: Fri, 13 Apr 2018 12:32:30 +0800
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.
