5df1ee4594 arm: mvebu : sata_mv should probe all ports
While a board could have multiple SATA ports, some of the ports might
not have a disk attached to them. So while probing for disks,
sata_mv_probe() should continue probing all ports, and skip one with
no disk attached.

Tests with:

- Seagate Goflex Net (Marvell Kirkwood 88F6281) out-of-tree u-boot.
- Zyxel NSA325 (Marvell Kirkwood 88F6282 out-of-tree u-boot.

Observation:

If a board has 2 or more SATA ports, and there is only one disk
attached to one of the ports, sata_mv_probe() does not return
a successful probe status. And if only one disk is attached to the
2nd port (i.e. port 1), it is not probed at all.

Patch Description:

Let sata_mv_probe() continues probing all ports, even if there
is error in probing a given port, and then return a successful
status if there is at least one port was probed successfully.

7940d9628a arm: mvebu: sata_mv failed to identify HDDs during cold start
During cold start, with some HDDs, mv_sata_identify() does not populate
the ID words on the 1st ATA ID command. In fact, the first ATA ID
command will only power up the drive, and then the ATA ID command
processing is lost in the process.

Tests with:

- Seagate ST9250320AS 250GB HDD and Seagate ST4000DM004-2CV104 4TB HDD.
- Zyxel NSA310S (Kirkwood 88F6702), Marvell Dreamplug (Kirkwood 88F6281),
 Seagate GoFlex Home (Kirkwood 88F6281), Pogoplug V4 (Kirkwood 88F6192).

Observation:

- The Seagate ST9250320AS 250GB took about 3 seconds to spin up.
- The Seagate ST4000DM004-2CV104 4TB took about 8 seconds to spin up.
- mv_sata_identify() did not populate the ID words after the call to
 mv_ata_exec_ata_cmd_nondma().
- Attempt to insert a long delay of 30 seconds, ie. mdelay(30_000), after
the call to ata_wait_register() inside mv_ata_exec_ata_cmd_nondma() did
not help with the 4TB drive. The ID words were still empty after that 30s
delay.

Patch Description:

- Added a second ATA ID command in mv_sata_identify(), which will be
executed if the 1st ATA ID command did not return with valid ID words.
- Use the HDD drive capacity in the ID words as a successful indicator of
ATA ID command.
- In the scenario where a box is rebooted, the 1st ATA ID command is always
successful, so there is no extra time wasted.
- In the scenario where a box is cold started, the 1st ATA command is the
power up command. The 2nd ATA ID command alleviates the uncertainty of
how long we have to wait for the ID words to be populated by the SATA
controller.

2361b5eb5c ata: ahci: fix ahci_link_up() type mismatch for LTO
When building highbank_defconfig with LTO, the compiler complains about
type mismatch of function ahci_link_up().

The third parameter of this function is of type u8 in
drivers/ata/ahci.c, but of type int in board/highbank/ahci.c.

There is no reason in using u8, and the code using this function
actually passes an int variable into the function (so it is implicitly
converted to u8).

Change the type of this parameter to int in drivers/ata/ahci.c.

1eefd49cc1 sata: ahci_mvebu.c: Enable AHCI/SATA driver for MIPS Octeon
This patch enables the usage of the MVEBU AHCI/SATA driver. The only
changes necessary to support MIPS Octeon via DT based probing are, to
add the compatible DT property and the use of dev_remap_addr() so that
the correct mapped address is used in the Octeon case (phys != virt).

Please note that this driver supports the usage of the "scsi" command
and not the "sata" command, since it does not provide an own "scan"
function, which is needed for the "sata" cmd support.

of its operand. This occurs as the logical operand of !

When DIAG_X is set, the PHY COMINIT signal is detected, so
should use '&' to check whether it is set.

5ff78d11e5 Revert "ata: fsl_ahci: Add sata DM support for Freescale powerpc socs"
This reverts commit 1ee4942918.

Commit 1ee4942918 ("ata: fsl_ahci: Add sata DM support for Freescale
powerpc socs") introduced SCSI layer to call AHCI private API in order
to support sata operations, In DM mode, This is not necessary for
non-AHCI sata. So revert it and have already updated the driver itself
to operate sata directly.

964b90f61d ata: fsl_sata: Continue probing other sata port when failed current port.
In the initialization of sata driver, we want to initialize all port
 probes, Therefore, any detection failure between of them should continue
 initialization by skipping the current port instead of exit.

use SATA_SIL with DM,

Also fix below warning while PowerPC P series boards compilation,

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."
