Change in flashrom[master]: flash.h,flashchips.c: add writeprotect bit layout map to chips
by Nikolai Artemiev (Code Review) 24 Feb '22

Attention is currently required from: Nico Huber, Angel Pons, Nikolai Artemiev, Sergii Dmytruk. 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/+/58477 to look at the new patch set (#33). Change subject: flash.h,flashchips.c: add writeprotect bit layout map to chips ...................................................................... flash.h,flashchips.c: add writeprotect bit layout map to chips This patch adds a register bit map `struct reg_bit_info`, with fields for storing the register, bit index, and writability of each bit that affects the chip's write protection. This allows writeprotect code to be independent of the register layout of any specific chip. The new fields have been filled out for example chips. The representation is centered around describing how bits can be accessed and modified, rather than the layout of registers. This is generally easier to work with in code that needs to access specific bits and typically requires specifying the locations of fewer bits overall.
