Add support for expanding simple expressions and sizes such as
"(4 * 1024)", "(512 << 10)" or "(SZ_256K)".
This can help to significantly reduce the number of "suspicious"

If the expansion fails, it falls back to the original string.

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.

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.

It is annoying to have to set up and maintain two sets of toolchains, one
for buildman and one for moveconfig.
Adjust moveconfig to make use to buildman's toolchains. This should make
things easier.
One missing feature is the ability to specify the toolchain on the command
line with a special environment variable, e.g. CROSS_COMPILE_ARM. I'm not
sure if that is useful, but if it is it could be implemented in buildman.

It is useful to be able to process only a subset of boards to save time.
Often that subset is defined by the defconfig files in a git commit. This
change allows things like:
# Build the database
./tools.moveconfig.py -b
# Find some implying configs
./tools/moveconfig.py -i CONFIG_X
# Add some 'imply' statements to Kconfig files
./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B
# Reprocess the defconfig files to see if we can drop some changes
git show --stat | ./tools/moveconfig.py -s -d -
# Update the commit, with fewer defconfig changes
gii commit -au
Where the commit contains defconfig files, this will reprocess them to
take account of the imply statements that you added.

Some CONFIG options can be implied by others and this can help to reduce
the size of the defconfig files. For example, CONFIG_X86 implies
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
each of the x86 defconfig files.
Add a -i option which searches for such options.

Prior to this commit, the tool could not move options guarded by
CONFIG_SPL_BUILD ifdef conditionals because they do not show up in

which is probably preferred behavior when moving options for SPL.

Currently, the tool gives up moving an option quietly if its entry
was not found in Kconfig.
If the option is not defined in the config header in the first
place, it is no problem (as the Kconfig entry may have been hidden
by reasonable "depends on").
However, if the option is defined in the config header, the missing
Kconfig entry is a sign of possible behavior change. It is highly
recommended to manually check if the option has been moved as
expected. In this case, let's add "suspicious" in the log and
change the log color (if --color option is given) to make it stand
out.
This was suggested by Tom in [1].

We mostly move config options from board header files to Kconfig,
but sometimes config defines come from CONFIG_SYS_EXTRA_OPTIONS.
Historically, CONFIG_SYS_EXTRA_OPTIONS originates in boards.cfg,
which was used as a central database of configuration prior to the
Kconfig conversion.
Now, we want to migrate to primary entries in Kconfig rather than
option list in CONFIG_SYS_EXTRA_OPTIONS, so it should be helpful to
have the tool to cleanup CONFIG_SYS_EXTRA_OPTIONS automatically.

The tools/moveconfig.py has a feature to cleanup #define/#undef's
of moved config options, but I want this tool to do a better job.
For example, when we are moving CONFIG_FOO and its define is
surrounded by #ifdef ... #endif, like follows:
#ifdef CONFIG_BAR
# define CONFIG_FOO
#endif
The header cleanup will leave empty #ifdef ... #endif:
#ifdef CONFIG_BAR
#endif
Likewise, if a define line between two blank lines
<blank line>
#define CONFIG_FOO
<blank lines.
... is deleted, the result of the clean-up will be successive empty
lines, which is a coding-style violation.
It is tedious to remove left-over garbage lines manually, so I want
the tool to take care of this. The tool's job is still not perfect,
so we should check the output of the tool, but I hope our life will
be much easier with this patch.

There are some cases where config options are moved, but they are
ripped off at the final savedefconfig stage:
- The moved option is not user-configurable, for example, due to
a missing prompt in the Kconfig entry
- The config was not defined in the original config header despite
the Kconfig specifies it as non-bool type
- The config define in the header contains reference to another
macro, for example:
#define CONFIG_CONS_INDEX (CONFIG_SYS_LPC32XX_UART - 2)
The current moveconfig does not support recursive macro expansion.
In these cases, the conversion is very likely to be an unexpected
result. That is why I decided to display the log in yellow color
in commit 5da4f857be ("tools: moveconfig: report when CONFIGs are
removed by savedefconfig").
It would be nice to display the list of suspicious boards when the
tool finishes processing. It is highly recommended to check the

This option allows the 'make autoconf.mk' step to run against a former
repo state, while the savedefconfig step runs against the current repo
state. This is convenient for the case where something in the Kconfig
has changed such that the defconfig is no longer complete with the new
Kconfigs. This feature allows the .config to be built assuming those old
Kconfigs, but then savedefconfig based on the new state of the Kconfigs.
If in doubt, always specify this switch. It will always do the right
thing even if not required, but if it was required and you don't use it,
the moved configs will be incorrect. When not using this switch, you
must very carefully evaluate that all moved configs are correct.
