This doesn't explain anything. Why do we need that? If anything we
should rather get rid of that NVRAM firmware driver. It was needed
before we had all NVMEM stuff in place. Finally how can reading
iomem break mtd/ubi?!
It seems like some hack instead of proper fix. Possibly because of lack
of understanding the issue / some subsystem.

Did you take a look at the bootlog on this post on the thread, I've
mentioned your user handle a few times but received no response on the
forum.

Well, it doesn't really matter *in context* of getting this patch
accepted for mainline. It needs to be properly described on its own so
people can review it without looking through dozens of forum posts.
Sorry for not following that closely, I lagged behind due to my work on
other Broadcom topics. Broken LZMA, broken Linksys device support,
broken BCM5358. I'll see if I can figure out sth from that thread.
