+/*
+ * Just get started by jumping to CONFIG_ETRAX_PTABLE_SECTOR to start
+ * kernel decompressor.
+ *
+ * In practice, this only works for NOR flash (or some convoluted RAM boot)
+ * and hence is not really useful for Artpec-3, so it's Etrax FS / NOR only.
  *
- * This used to be the rescue code but now that is handled by the
- * RedBoot based RFL instead. Nothing to see here, move along.
