Anastasia Klimchuk has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/84686?usp=email ) Change subject: erase/write: Deselect all smaller blocks when large block is selected ...................................................................... erase/write: Deselect all smaller blocks when large block is selected Previously the logic which selected large block did deselect of smaller blocks, but only one level below. So some even smaller blocks could still remain selected, and this would result in duplicate erase.
