Attention is currently required from: Nico Huber, Edward O'Callaghan, Anastasia Klimchuk, Nikolai Artemiev. Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/58479 to look at the new patch set (#7). Change subject: [RFC] writeprotect: add functions to read and write wp_chip_state ...................................................................... [RFC] writeprotect: add functions to read and write wp_chip_state The functions map between register values and `struct wp_chip_state` using the chip's register bit map. All currently supported chips can be handled with a single pair of read/write functions, though an option for chips to override them might be necessary in the future.

Change in flashrom[master]: [RFC] flashchips: add writeprotect bit layout map to chips
by Nikolai Artemiev (Code Review) 04 Nov '21

04 Nov '21

Attention is currently required from: Nico Huber, Edward O'Callaghan, Angel Pons, Nikolai Artemiev. Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/58477 to look at the new patch set (#7). Change subject: [RFC] flashchips: add writeprotect bit layout map to chips ...................................................................... [RFC] flashchips: add writeprotect bit layout map to chips This patch adds a register bit map `struct flashchip`, 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.

Change in flashrom[master]: [RFC] spi25_statusreg: make register read/write functions generic

Change subject: [RFC] spi25_statusreg: make register read/write functions generic ...................................................................... [RFC] spi25_statusreg: make register read/write functions generic This patch adds new spi_{read,write}_register() functions that take the source/destination register as an argument. Currently they can only access SR1, support for other registers will be added in another patch. Since we're refactoring things, this commit also makes spi_read_register() return an error code, making it possible to identify error conditions that spi_read_status_register() concealed.
