Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, Sergii Dmytruk,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/58480
to look at the new patch set (#41).
Change subject: flashchips,writeprotect_ranges: add range decoding function
......................................................................
flashchips,writeprotect_ranges: add range decoding function
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.

writeprotect, cli_classic: delete old writeprotect code
Delete writeprotect code that was previously extracted from the cros tree.
This is the first of a series of commits adding writeprotect support.
Following commits incrementally implement writeprotect operations,
culminating in writeprotect support for three example chips: GD25LQ128,
GD25Q32, and GD25Q256.

libflashrom,writeprotect: add functions for reading/writing WP configs
New functions are exposed through the libflashrom API for
reading/writing chip's WP settins: `flashrom_wp_{read,write}_cfg()`.
They read/write an opaque `struct flashrom_wp_cfg` instance, which
includes the flash protection range and status register protection mode.
This commit also adds `{read,write}_wp_bits()` helper functions that
read/write chip-specific WP configuration bits.

cli_classic: Replace programmer_shutdown() with libflashrom call
flashrom_programmer_shutdown(NULL) is an equiv call
to programmer_shutdown() however this further decouples
cli from flashrom core logic at link-time, prefering to
instead enter via libflashrom instead.
