Gregory,

Adding devicetree-discuss.

Guys, how do you prefer to handle plug-in RAM modules?  describe the
soldered-in amount, or?

Well, there's something we don't encounter too much in the embedded
world.  ;-)  I'm inclined to think the entry here should be the soldered

the probed amount.  But I haven't seen a precedent set yet...
