a44ca1346d ARM: imx6: update 1GB DDR3 calibration for DHCOM i.MX6qd PDK
The existing calibration values were found to be incorrect
in comparison to newly determined values.

The new values were generated with the help of 5 boards. They have
been determined with the NXP Utility 'DDR Stress Test (2.9.0)'.

3d81584d40 Revert "ARM: imx6: Disable DDR DRAM calibration DHCOM i.MX6 PDK"
This reverts commit a637fe6f27.

The DDR DRAM calibration was enhanced by write leveling correction code.
It can be used with T-topology now.

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.

d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

commit f411b5cca4 ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.

b979e35230 ARM: imx6: Adjust DDR DRAM settings on DHCOM i.MX6 PDK
The board uses T-topology for the four x16 DRAM chips, so remove
the write-leveling from the SPL as that is only usefly on fly-by
topology and can be harmful on T-topology. Also update the DRAM
timing with values from calibration on multiple boards.

79df00fdb4 MAINTAINERS: Add missing boards and config entries
As part of my usual round of build testing, output about missing
MAINTAINERS information was not logged, and thus often overlooked.
Correct that mistake by ensuring that I log the output of
genboardscfg.py every time.  As part of that, address a number of
missing MAINTAINERS entires.  In the case of a missing file, I have put
the original submitter down.  In the rest of the cases I have added the
config (and sometimes relevant header file) to the existing set of file
globs.
