You don't actually need to define this to have a value.

This is something I am wondering about (btw. you might have seen a FIXME tag in
my repository right next to this code). Do we really need this in U-Boot or is

Anyway, I will pick them in my tree and add a bit more magic sause to them ,
then re-post the whole series.
