Hi Greg.

I'm not a user but thought I would give it a once over to see what you  
were carrying.

That doesn't quite add up to 32MB.  Should that be 0x1FE0000 or
is the last 0x1E0000 (1920k) supposed to be reserved too?  Again,
I am not a user.

Lots of people turn on EMBEDDED for lots of reasons, asking about
a lot more drivers seems burdensome.

Care to create a single intermediate Kconfig var for those?
Something like "Controllers attached directly to a cpu?"

This would then depend on your directly attached config and you
could have both it and pci configured.

Sees this undoes part of the benefit, perhaps you should add a
third option.
