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.

3759df0c08 tools: Update python "help" tests to cope with "more" oddities
In some cases when "more" is told to page a given file it will prepend
the output with:
::::::::::::::
/PATH/TO/THE/FILE
::::::::::::::

And when this happens the output will not match the expected length.
Further, if we use a different pager we will instead fail the coverage
tests as we will not have 100% coverage.  Update the help test to remove
the string in question.

4e1102f6de kconfiglib: update with 'imply' support
Corresponds to 375506d (File writing nit) from upstream
(https://github.com/ulfalizer/Kconfiglib).

Adds proper 'imply' support and fixes a few minor issues, one of which
previously triggered the following weird warning:

  configs/taurus_defconfig: /tmp/tmpisI45S:6: warning: assignment to SPL_LDSCRIPT changes mode of containing choice from "arch/$(ARCH)/cpu/u-boot-spl.lds" to "y"

The change in 8639f69 (genconfig.py: Print defconfig next to warnings)
was reapplied.

tools/moveconfig.py previously depended on a hack that merged 'select's
with 'imply's. It was modified to look at the union of
Symbol.get_selected_symbols() and Symbol.get_implied_symbols(), which
should give the same behavior.

tools/genboardscfg.py was verified to produce identical board.cfg's
before and after the change.

daab59ac05 avr32: Retire AVR32 for good
AVR32 is gone. It's already more than two years for no support in Buildroot,
even longer there is no support in GCC (last version is heavily patched 4.2.4).

Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully).

There is no good point to keep this support in U-Boot either.

b50113f373 buildman: Add an option to just create the config
Normally buildman does a full build of a board. This includes creating the
u-boot.cfg file which contains all the configuration options. Buildman uses
this file with the -K option, to show differences in effective configuration
for each commit.

Doing a full build of U-Boot just to create the u-boot.cfg file is wasteful.
Add a -D option which causes buildman to only create the configuration. This
is enough to support use of -K and can be done much more quickly (typically
5-10 times faster).

c8785c5b49 buildman: Avoid overwriting existing toolchain entries
The current code for setting up the toolchain config always writes the new
paths to an item called 'toolchain'. This means that it will overwrite any
existing toolchain item with the same name. In practice, this means that:

   buildman --fetch-arch all

will fetch all toolchains, but only the path of the final one will be added
to the config. This normally works out OK, since most toolchains are the
same version (e.g. gcc 4.9) and will be found on the same path. But it is
not correct and toolchains for archs which don't use the same version will
not function as expected.

Adjust the code to use a complete glob of the toolchain path.

f79f1e0c0e buildman: allow more incremental building
One use-case for buildman is to continually run it interactively after
each small step in a large refactoring operation. This gives more
immediate feedback than making a number of commits and then going back and
testing them. For this to work well, buildman needs to be extremely fast.
At present, a couple issues prevent it being as fast as it could be:

1) Each time buildman runs "make %_defconfig", it runs "make mrproper"
first. This throws away all previous build results, requiring a
from-scratch build. Optionally avoiding this would speed up the build, at
the cost of potentially causing or missing some build issues.

2) A build tree is created per thread rather than per board. When a thread
switches between building different boards, this often causes many files
to be rebuilt due to changing config options. Using a separate build tree
for each board would avoid this. This does put more strain on the system's
disk cache, but it is worth it on my system at least.

This commit adds two command-line options to implement the changes
described above; -I ("--incremental") turns of "make mrproper" and -P
("--per-board-out-dir") creats a build directory per board rather than per
thread.

Tested:

    ./tools/buildman/buildman.py tegra
    ./tools/buildman/buildman.py -I -P tegra
    ./tools/buildman/buildman.py -b tegra_dev tegra
    ./tools/buildman/buildman.py -b tegra_dev -I -P tegra

... each once after deleting the buildman result/work directory, and once
"incrementally" after a previous identical invocation.
