At present buildman only supports building the default target. Generally
this is what is wanted, but in some cases boards erroneously have a
different target for product extra files.
Add a --target option to help. Also add a comment indicating which
letters are free for new options.

For most boards, the device-tree compiler is built in-tree, ignoring the
system version. Add a special option to skip this build. This can be
useful when the system dtc is up-to-date, as it speeds up the build.

There are operations in buildman that result in running the cross-tools
(such as performing size checks) and now that we have not modified PATH
to know where our tools are, these operations fail.
This reverts commit 6c0a3cf75f72370deec3ee516a9dd377397af207.

The feature to set the toolchain path does not seem to be needed. It
causes problems with venv (see [1]). Let's remove it.
Add some tests while we are here.
It does not look like any docs changes are needed for this.

Buildman uses all available CPUs by default, so running more than one or
two concurrent processes is not normally useful.
However in some CI cases we want to be able to run several jobs at once
to save time. For example, in a lab situation we may want to run a test
on 20 boards at a time, since only the build step actually takes much
CPU.
Add an option which allows such a limit. When buildman starts up, it
waits until the number of running processes goes below the limit, then
claims a spot in the list. The list is maintained with a temporary file.
Note that the temp file is user-specific, since it is hard to create a
locked temporary file which can be accessed by any user. In most cases,
only one user is running jobs on a machine, so this should not matter.

When a file is removed by a commit (e.g. include/common.h yay!) it can
cause incremental build failures since one of the dependency files from
a previous build may mention the file.
Add an option to run 'make mrproper' automatically when a build fails.
This can be used to automatically resolve the problem, without always
adding the large overhead of 'make mrproper' to every build.

This is quite a useful thing to use when building since it avoids small

Bring this tool into buildman, so we don't have to run it separately. The
board.cfg file is still produced as part of the build, to save time when
doing another build in the same working directory. If it is out of date
with respect to the Kconfig, it is updated.
Time to regenerate on a recent single-thread machine is 4.6s (1.3s on a
32-thread machine), so we do need some sort of cache if we want buildman
to be useful on incremental builds. We could use Python's pickle format
but:
- it seems useful to allow boards.cfg to be regenerated, at least for a
while, in case other tools use it
- it is possible to grep the file easily, e.g. to find boards which use
a particular SoC (similar to 'buildman -nv <soc>'

Add a -a option to specify changes to the config before the build
commences. For example
buildman -a ~CONFIG_CMDLINE
disables CONFIG_CMDLINE before doing the build.

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.

Sometimes we don't want buildman to return failure if it seems warnings.

produced by U-Boot, such as:

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.

When using #define CONFIG_SOME_OPTION, the value it set to '1'. When using
defconfig (i.e. CONFIG_SOME_OPTION=y) the value is set to 'y'. This results

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.
