1) Add function to flatten out the addresses of the flash chip as per
the different erase functions. This function will return a list of
layouts which is dynamically allocated. So after use all the layouts as
well as the list itself should be freed. The free_erase_layout function
does that.
2) Add function to align start and end address of the region (in struct
walk_info) to some erase sector boundaries and modify the region start
and end addresses to match nearest erase sector boundaries. This
function will be used in the new algorithm for erase function selection.
3) Add function that returns a list of sectors (as seen by the first
erase function) that need erasing.
4) Add a function to call the erase algorithm.

Add a bash script for the flashrom CLI that auto-completes the command
sequence. The script is generated from a template by substituting a
list of enabled programmers. It requires an extra `bash-completion`
package to work, but, fortunately, it's installed on most systems.
Build system changes:
meson:
provide option `bash_completion` to determine if the script should
be installed (depends on option `classic_cli`).
makefile:
make a list of enabled programmers (by using CONFIG_* variables)
to do substitution manually

These specific git hooks are only needed when someone wants to push a
patch to upstream and so it's not needed to run it in every make call.
Beside that, we also don't know the environment in which this is
executed and it might not be wanted.
Thus, add a new make target `gitconfig` and move the install command to
it. It can be used by running `make gitconfig`.

This code was originally introduced by ITE for now exceedingly old
Chromebooks. The code has had very little attention to maintain it,
unlikely tested for a long time and now seems to be just a technical
burden to the flashrom project.
If someone is later interested it could be resurrected for reference
from git history. However, it needs quite a bit of work to bring it back
into maintainable order.

moved to cli_*.c and is not used for libflashrom. Therefore we can drop

Allow chips to specify functions that map status register bits to
protection ranges. These are used to enumerate available ranges and
determine the protection state of chips. The patch also adds a range
decoding function for the example chips. Many other chips can also be
handled by it, though some will require different functions (e.g.
MX25L6406 and related chips).
Another approach that has been tried in cros flashrom is maintaining
tables of range data, but it quickly becomes error prone and hard to
validate.
Using a function to interpret the ranges allows compact encoding with
most chips and is flexible enough to allow chips with less predictable
ranges to be handled as well.
