Some of t1042 boards fails DDR init with an Automatic calibration error
every now and then. Investigations revealed that true Warm boots
never failed. Warm boots has some extra steps performed, one being
to start DDRC in Self Refresh and then clearing SR right after.
Applying this SR method unconditionally made all our boards
stable again, regardless of Cold/Warm boot.

DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. When DM_I2C_COMPAT is not enabled for
compilation, a compilation error will be generated. This patch solves
the problem that the i2c-related api of the lx2160a platform does not
support dm.

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.

DDR controllers always use binding register to determine the memory
space to perform data initialization. In case of controller interleaving,
the space is doubled, resulting twice long wait. It wasn't too bad until
the memory capacity increases. To reduce the wait time, reduce the
binding space to half and restore it after data initialization.
Three-way interleaving is no longer used and is removed.

enable to be off.
Erratum A009803 requires the controller to be idel before enabling
