+
+Partitions are basically fixed indeed but firmware ones don't have
+hardcoded function ("firmware" vs "failsafe"). Actual function depends
+on bootloader configuration. Use a proper binding for that.
+
+While at it fix numbers formatting to avoid:
+arch/arm/boot/dts/bcm47094-linksys-panamera.dt.yaml: partitions: 'partition at 1F00000' does not match any of the regexes: '^partition@[0-9a-f]+$', 'pinctrl-[0-9]+'
+        From schema: Documentation/devicetree/bindings/mtd/partitions/linksys,ns-partitions.yaml
