Patches added to 4xx next branch

[Josh Boyer]

Hi All,

The following patches have been added to the next branch of the 4xx
tree.  I plan on letting them sit in there for a few days and then
asking Paul to pull into his tree.  That way if I've screwed something
up only poor Stephen will get hit by it and I can fix things without
causing major problems for others.

I have a few more patches to add, but nothing really major.  If the
outstanding questions on sam440ep are answered/fixed then that will
likely go in too.  If there are things I've missed, please let me know.
