-Subject: [PATCH] nvmem: qfprom: Don't touch certain fuses
-
-Some fuse ranges are protected by the XPU such that the AP cannot
-access them. Attempting to do so causes an SError. Use the newly
-introduced per-soc compatible string, and the newly introduced
-nvmem keepout support to attach the set of regions
-we should not access.
