-Subject: [PATCH 16/18] util/ifdtool: add --nuke flag (all 0xFF on region)
-
-When this option is used, the region's contents are overwritten
-with all ones (0xFF).
-
-Example:
-
-./ifdtool --nuke gbe coreboot.rom
-./ifdtool --nuke bios coreboot.com
-./ifdtool --nuke me coreboot.com
-
-Rebased since the last revision update in lbmk.
