Change in flashrom[master]: flashchips,writeprotect_ranges: add range decoding function

Please visit https://review.coreboot.org/c/flashrom/+/58480 to look at the new patch set (#25). 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.

Change in flashrom[master]: flashchips: add writeprotect bit layout map to chips

Change subject: flashchips: add writeprotect bit layout map to chips ...................................................................... flashchips: 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.

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

Please visit https://review.coreboot.org/c/flashrom/+/58475 to look at the new patch set (#17). Change subject: spi25_statusreg: make register read/write functions generic ...................................................................... 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. This also removes the initial 100ms delay between writing a register and the first attempt to check the chip's status. An initial delay was added to avoid needing to read the status register multiple times, but that is unlikely to cause problems on modern flash chips.
