Call the function before tcsetattr() settings are known, then again with settings prepared but not yet applied and finally a third time after tcsetattr(). Darwin support needs this change; there custom_baud code must be called to modify the settings passed to tcsetattr() and then again after tcsetattr() returns. The change should be non-functional on all currently supported systems; current code calls set_custom_baudrate() before any tcsetattr() settings are prepared, so we have three stages in total. This change originates from discussion of the macOS patch proposed by Denis Ahrens in https://review.coreboot.org/c/flashrom/+/67822 Change-Id: I40cc443cfb7bf6b212b31826d437b898cc13c427 Signed-off-by: Peter Stuge <peter@stuge.se> Reviewed-on: https://review.coreboot.org/c/flashrom/+/70569 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Thomas Heijligen <src@posteo.de>
