Maybe use WARN so that the warning is more verbose and kernel gets tainted?
Well I was hoping to avoid annoying people with the trace.
But can do that if people prefer that, what do others think?
WARN is better and eye catchy. Also, could we add information on when
the support will be removed since we call it deprecated?
Well quoting the hostage situation from a Mr. Show episode
"Now Who Wants Ice Cream?" the answer to that would be:

OK, you want me to guess? A hundred million days, or maybe ten more
minutes, somewhere in there, I just can't say, don't know.
How about ~1 year? We have been talking about dt only boot for over an
year already... Can we say 3.22 kernel, platforms that are not converted
to device tree only loose legacy boot support. 
I'm hoping we can make it faster let's say over next two merge
windows. Pretty much everything already works with device tree
booting so now it's just a question of getting people to start
using it and fix whatever issues we may encounter.

Regards,

Tony
