[PATCH] of: add some debugging statements if initrd isn't found

From: Andres Salomon
Date: Fri Feb 03 2012 - 17:24:10 EST



While debugging initrd problems in a FDT blob, it's nice to both terminate
the "Looking for initrd properties... " with a newline, as well as letting us
know which property wasn't found.
