Yes. The code is needed for bcm63xx embedded devices. The code that uses
it currently is not in mainline, though. It can be found in the OpenWRT
repositories.

But I still think that the SPROM fallback mechanism should be replaced
by a "platform data" based mechanism, or similar. Just removing it
without replacement is not an option, because bcm63xx embedded really
does not have an SPROM.

The bcm63xx was the reason the fallback mechanism was implemented in
the first place. See git logs for more details.
