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.

The initial implementation of mx6memcal reset the CPU after
running the memory calibration procedure because the generic
board has no information about which boot devices are available.
Now that we have SDP support in SPL, use it to allow a full
U-Boot to be uploaded (i.e. to use "mtest").

Currently mmdc_do_dqs_calibration() and mmdc_do_write_level_calibration()
show the same error message, which is confusing for debugging.
Disambiguate the mmdc_do_dqs_calibration() error message.

This is a virtual "board" that uses configuration files and
Kconfig to define the memory layout used by a real board during
the board bring-up process.
It generates an SPL image that can be loaded using imx_usb or
SB_LOADER.exe.
When run, it will generate a set of calibration constants for
use in either or both a DCD configuration file for boards that
use u-boot.imx or struct mx6_mmdc_calibration for boards that
boot via SPL.
In essence, it is a configurable, open-source variant of the
Freescale ddr-stress tool.

File mx6memcal_defconfig configures the board for use with
mx6sabresd or mx6qsabreauto.
