[POWERPC] QE: get rid of most device_types and model
Anton Vorontsov [Thu, 24 Jan 2008 15:39:59 +0000 (18:39 +0300)]
Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data"
and "fsl,qe-ic".

Unfortunately it's still impossible to remove device_type = "qe"
from the existing device trees because older u-boots are looking for it.
