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. 

If you want to define some date, it should be a calendar date instead
of some kernel version based on guesswork (you cannot really predict
the kernel versions for future, just remember the 2.6.39 -> 3.0 change).

Also, you cannot expect all kernel users to know what you have been
talking about. E.g. OMAP DMA API deprecation may have been discussed
before, but I only learned it after the WARN appeared in the kernel tree.
So you should start counting from that.

Personally I don't mind if you delete OMAP3 legacy boot support already
tomorrow morning, but if you want to give ~1 year transition period it
should end somewhere in the end of 2015. Of course if there are no legacy
boot users you can do it faster.
