Come on, Wolfgang.  Why do you think I posted this patch in the first
place?  I even said so in the title of patch: "make
fdt_increase_size() available to everyone".

You asked why the information would be board-specific, and I answered
that question.

Now I believe you're intentionally trying to be difficult.

Which is exactly why I want fdt_increase_size() to be available to everyone.

Exactly!  And the best way to do that is to make the function that
adds space to the fdt available to everyone.

How silly of me.  For a moment, I forgot that I was trying to improve U-Boot.
