    on the setup, so I think that the choice on what firmware to make
    persistent should be left to userspace.
 
+ - Why register_firmware()+__init can be useful:
+ 	- For boot devices needing firmware.
+	- To make the transition easier:
+		The firmware can be declared __init and register_firmware()
+		called on module_init. Then the firmware is warranted to be
+		there even if "firmware hotplug userspace" is not there yet or
+		it doesn't yet provide the needed firmware.
+		Once the firmware is widely available in userspace, it can be
+		removed from the kernel. Or made optional (CONFIG_.*_FIRMWARE).
+
+	In either case, if firmware hotplug support is there, it can move the
+	firmware out of kernel memory into the real filesystem for later
+	usage.
+
+	Note: If persistence is implemented on top of initramfs,
+	register_firmware() may not be appropriate.
