Needs GPLv2 or later boilerplate.

Just #define CONFIG_FOO in these cases (and some others that follow)

That's not right :)

This isn't your mistake initially, but this should just be start of
memory to smallest possible config the evm can come with - 4MB.

Just leave it out.

Leave that out and get the generic table.  am335x needs to be updated
for that.

LOL, indeed..forgot about that am335x specific stuff. Will fix.

Ok, will do. I even saw something about this and forgot to update this
config.
