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 unit test checks if a device tree is installed. It requires that the
'compatible' property of the root node exists. If available it prints the
'serial-number' property.

The serial-number property is derived from the environment variable
'serial#'. This can be used to check if the image_setup_libfdt() function
is executed.

A Python test is supplied. It sets a value for serial# and checks that the
selftest shows this as serial-number.

Currently, if a test emits a warning message but otherwise passes, there's
no indication of this in the log summary, which can lead to warnings being
missed. Enhance the test logic to explicitly mention warnings in otherwise
passing tests, and not to collapse the log sections for tests with
warnings, so that they're more easily seen when scanning the log.

Add a standalone MMC block read test. This allows direct testing of MMC
access rather than relying on doing so as a side-effect of e.g. DFU or
UMS testing, which may not be enabled on all platforms.

Add a test of the 'log format' and 'log rec' commands. This also covers

Fix a style nit in the tests also.
