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.

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.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

This patch adds DM support to the Armada XP SATA driver. This is needed
to enable CONFIG_BLK on this platform. 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 and the creation of the corresponding BLK
devices.
This conversion is done to get rid of the compile warning:

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
