Change in flashrom[master]: buspirate: Add option for setting the aux pin
by Sean Anderson (Code Review) 09 Mar '23

09 Mar '23

Sean Anderson has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/43608 ) Change subject: buspirate: Add option for setting the aux pin ...................................................................... buspirate: Add option for setting the aux pin This adds a parameter to drive the aux pin low (or high if you explicitly want the previous behavior). Some boards need to have a reset pin driven low before the firmware can be safely flashed. With the Bus Pirate, this is most easily done with the auxiliary pin.
