Use DT /aliases node to establish a stable phandle to the configuration
EEPROM. This permits the configuration EEPROM to be moved e.g. to a
different address or a different bus. Adjust the board code to handle
new phandle lookup.

This patch enables DM I2C for DHCOM i.MX6 PDK2 boards and
removes non DM I2C code. The I2C EEPROM with ethaddr (MAC)
is defined in the device tree. Use UCLASS_I2C_EEPROM
to find the device by fixed hardware path and read the ethaddr.
Tested with DHCOM i.MX6dl and DHCOM i.MX6q.

It turned out that after a reset the boot process from the spi bootflash is
disturbed by other spi slave devices connected to DHCOM SPI1, which uses the
same spi interface with a different SS line.
Therefore the pad pull ups are enabled.

The four x16 DDR3 are wired in T-topology. From NXP AN4467:
'Although not required, T-Topologies may also benefit from performing
Write Leveling as there are package delays on both the processor and DDR
devices that can be de-skewed by performing Write Leveling. Therefore,
Freescale recommends determining Write Leveling calibration parameters
for all boards, regardless of topology used.'
That is why write level calibration is also done.

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.

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 f411b5cca48f ("board: am335x: Always set eth/eth1addr environment
variable")
when Ethernet is required in Linux, but not U-Boot.

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.

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.
