Change in flashrom[master]: dummyflasher: make RO status of SPI_SR_WEL explicit
by Sergii Dmytruk (Code Review) 19 Dec '21

19 Dec '21

Sergii Dmytruk has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/60224 ) Change subject: dummyflasher: make RO status of SPI_SR_WEL explicit ...................................................................... dummyflasher: make RO status of SPI_SR_WEL explicit It was read-only before this commit because it's reset at the bottom of emulate_spi_chip_response() for any command that's not WREN or EWSR. However, the code looked like it could be set by WRSR. This also adds a test which passes with and without this commit, but is probably still useful for the peace of mind.
