The SAMA5 support has no driver for the secure fuse peripheral. Kconfig allows you to “enable” it but there’s no underlying code.
Before I go ahead and create a character driver for this, is the omission for a “good” reason? The driver would handle the relatively straightforward management of programming the fuses, as well as obviously allowing you to read values. If another arch has anything similar please point me in its direction so I can create one that’s similar. Thanks, TimJTi.
