That's a very uninformative commit message. :)

How about putting a brief description of the AMCC 460 family in here?

Paul.

You're right. I was a little bit lazy. :)

I'll add some more text to the commit messages and resubmit in a short while.

Best regards,

It's rather boring at the moment.  460EX and 460GT are using a 440
core.  But mentioning that is also important I would think.
