FLAGS_HELP="
Command to update the firmware version for a board.

Updates the firmware version configuration for a board's
master configuration (program.star) and for selected projects
that include the master configuration.

If no projects are specified, all projects for that board are selected.
An optional skip list can be specified to skip selected boards.

The configurations for the selected projects are regenerated,
and the firmware manifest are updated for the projects.

The necessary CLs for these changes are created and uploaded for review.
An optional reviewer can be specified to send all the CLs to.

To correctly update the version, the config files must have existing version
configuration lines in them that the script can find and replace.
These lines are in the form of (e.g):

...
   major_version = 12345,
   minor_version = 10
   rw_major_version = 13579,
   rw_minor_version = 20
...

The first 2 lines represent the RO version, and the next are the RW version.

The regular expressions used to find and replace these configuration lines are
(for RO) "/${RO_MAJOR_RE}/" and "/${RO_MINOR_RE}/",
(for RW) "/${RW_MAJOR_RE}/" and "/${RW_MINOR_RE}/",
The version configuration lines must match these regular expressions.

These configuration lines may appear in the board's base program.star file, or in
the projects' config.star file. If the minor version is not 0, a 'minor_version' line
must exist in the files to be updated.

If the board's program.star file is updated (the default --program option), then carefully
check that the inherited project configs are correct, especially if projects are skipped.

If the --noprogram option is selected, then a config line of 'major_version' (and
'minor_version' if the minor version is not 0) must exist in the project config.star files.

Since the project's config is inherited from the board's program.star file, and can override
the version of the config, ensure that selectively updating either the program.star or
the project versions will not leave projects in an inconsistent state.
