The isAlive() method was deprecated in Python 3.8 and has been removed in
Python 3.9. See https://bugs.python.org/issue37804. Use is_alive() instead.
Since Python 2.6 is_alive() has been a synonym for isAlive(). So there
should be no problems for users using elder Python 3 versions.

This patch makes buildman create linked working trees instead of clones
of the source repository, but keeps updating the older clones of the
repository that might already exist. These worktrees share "everything
except working directory specific files such as HEAD, index, etc." with
the source repository. See the git-worktree(1) manual page for more
information.
If git-worktree isn't available, silently falls back to cloning the
repository.

Currently, the following scenario will rebuild the first commit even
though it is not really necessary - the commit sha or the position in the
patchset did not change:
$ git am <local-patch-0001>
$ tools/buildman/buildman -P -E -W -b master mx6
<do some more development work>
$ git am <local-patch-0002>
$ tools/buildman/buildman -P -E -W -b master mx6 <- will rebuild the first
commit as well, even
though nothing has
changed about it.
This is due to the fact that previous results directories get removed
when the number of commits change. By removing the _of_#_ part of the
directory path, the commits will be rebuilt only if the commit sha or the
position in the patchset changes. Also, update the testcase to reflect this
change.

At present buildman does not write its own output files (err, done, the

In fact ProduceResultSummary() reads the result from those files rather
than using the 'result' info directly. So ProcessResult() does not work
with -w at present. It does not print any output.

At present buildman defaults to running 'mrproper' on every thread before
it starts building commits for each board. This can add a delay of about 5
seconds to the start of the process, since the tools and other invariants
must be rebuilt.
In particular, a build without '-b', to build current source, runs much
slower without -I, since any existing build is removed, thus losing the
possibility of an incremental build.
Partly this behaviour was to avoid strange build-system problems caused by
running 'make defconfig' for one board and then one with a different
architecture. But these problems were fixed quite a while ago.
The -I option (which disabled mrproper) was introduced four years ago and
does not seem to cause any problems with builds.
So make -I the default and deprecate the option. To allow use of
'mrproper', add a new -m flag.

At present buildman removes any directory it doesn't intend to write
output into. This is overly expansive since if the output directory
happens to be somewhere with existing files, they may be removed. Using
an existing directory for buildman is not a good practice, but since the
result might be catastrophic, it is best to guard against it.
A previous commit[1] fixed this by refusing to write to a subdirectory
of the current directory, assumed to have U-Boot source code. But we can
do better by only removing directories that look like the ones buildman
creates.
Update the code to do this and add a test.

Something has changed in the last several month such that when buildman
builds U-Boot incrementally and a new CONFIG option has been added to the
Kconfig, the build hanges waiting for input:
Test new config (NEW_CONFIG) [N/y/?] (NEW)
Since binamn does not connect the build's stdin to anything this waits on
stdin to the build thread, which never comes. Eventually I suspect all the
threads end up in this state and the build does not progress.
Fix this by passing /dev/null as input to the build. That way, if there is
a new CONFIG, the build will stop (and fail):
Test new config (NEW_CONFIG) [N/y/?] (NEW)
Error in reading or end of file.

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.

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).

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.

At present buildman can compare configurations between commits but the
feature is less useful than it could be. There is no summary by architecture
and changes are not reported on a per-board basis.
Correct these deficiencies so that it is possible to see exactly what is
changing for any number of boards.
Note that 'buildman -b <branch> -C' is recommended for any build where you
will be comparing configuration. Without -C the correct configuration will
not be reported since changes will often not be picked up.
