Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/36433 ) Change subject: sb600spi.c: Don't access spibar directly ...................................................................... sb600spi.c: Don't access spibar directly Constrain the manner in which the global state of spibar is set and then subsequently accessed. This makes it easier to write unit-tests and instrument the code.

Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/38671 ) Change subject: programmer: Introduce programmer alias mechanism ...................................................................... programmer: Introduce programmer alias mechanism Originally introduced in the downstream commit ba0827acee4da6740133345f43aae386923bbaad . This was originally authored by David Hendricks so that the various flash peripheral in ChromeOS devices can be flashed. For example, flashrom -p ec -r ec.bin flashrom -p host -r host.bin Note that this requires, `CONFIG_DEFAULT_PROGRAMMER=PROGRAMMER_INTERNAL make` to be defined as build-time.
