Sorry, yes, but you mentioned above pending boards and not merged next 
branches. So my question was if you plan to change the warning after 
all pending boards and next branches are merged.

Because every non-U-Boot expert who just downloads recent git and 
compiles it will get the warning and will wonder if something is wrong 
or not. So yes, the check doesn't hurt, but the warning might confuse 
the users, which are non-experts.

It's similar to the "WARNING  - bad CRC or NAND, using default 
environment." runtime warning. There are tons on questions on various 
mailing lists if this is an error or not ;)

For OMAP3 I would enabled this option, independent of image size, just 
to get rid of the warning.
