83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

a22bbfda6e arm: mvebu: avoid possible NULL dereference
It does not make sense to check if info is NULL after
dereferencing it.

The problem was indicated by cppcheck.

2399e40120 arm: mvebu: AXP: Add possiblity to configure PEX detection pulse width
Tests have shown that on some boards the default width of the
configuration pulse for the PEX link detection might lead to
non-established PCIe links (link down). Especially under certain
conditions (higher temperature) and with specific PCIe devices
(in the case on the theadorable board its a Atheros PCIe WLAN
device). To enable a board-specific detection pulse width this weak
array "serdes_pex_pulse_width[4]" is introduced which can be
overwritten if needed by a board-specific version. If the board
code does not provide a non-weak version of this variable, the
default value will be used. So nothing is changed from the
current setup on the supported board.

Many thanks to Adam from Marvell for all his insights here and
his suggestion about testing with a changed detection pulse width.

beadff1731 mvebu: axp: refactor board_sat_r_get() and caller
Instead of calling board_sat_r_get() only for those boards providing the
satr11 value via I2C, call it for all boards and return static values
for those not using I2C.

In addition to that, make this a weak function to allow for board code
to override it.

e25d5a95e7 arm: mvebu: Make serdes setup on Armada XP less noisy
Change some of the PEX configuration output lines from always output to
only ouput upon specific debug enabling.

This changes the SPL output from:

U-Boot SPL 2016.01-rc2-00037-g9353a7f (Dec 10 2015 - 10:27:42)

Update PEX Device ID 0x78260

to:

Resulting in a little faster bootup time.

bf0db8b82a arm: mvebu: Add support for MV78260
This patch adds support for the dual core Armada XP variant, the
MV78260. It has some minor differences to the 4-core MV78460,
e.g. only 12 serdes lanes.

29b103c733 arm: mvebu: serdes: Move Armada XP SERDES / PHY init code into new directory
With the upcoming addition of the Armada 38x SPL support, which is not
compatible to the Armada XP SERDES init code, we need to introduce a new
directory infrastructure. So lets move the AXP serdes init code into
a new directory. This way the A38x code can be added in a clean way.
