Yes, thank you!

Agreed.

We also need to keep an eye on the big picture.  If we are going to
keep/maintain ixp4xx in the kernel, there are some things which need to
be done.  The drivers need moved to drivers/, platform headers need
moved to platform_data/, and we may as well add devicetree bindings
while we're moving things around.

Making ixp4xx compatible with multiplatform zImage would probably help
out the embedded distros as well.

thx,

Jason.
