fuses have already been programmed or are locked (if the SoC allows to

+- **fuse writebuff [-y] <addr>**
+ Programs fuse data using a structured buffer in memory starting at 'addr'.
+ This operation directly affects the fusebox and is irreversible.
+
+ The structure of the buffer should contain all necessary details for
+ programming fuses, such as the values to be written to the fuse, optional
+ metadata for validation or programming constraints and any configuration
+ data required for the operation. Define CONFIG_CMD_FUSE_WRITEBUFF to
+ enable the fuse writebuff command.
