68hc11/12/s12x/xgate patch

[Fred Cooke]

James,

Two things, for now:

1) Am I correct in saying that this is still one monolithic patch that
makes multiple changes to the port?

2) Am I correct in saying that this is still comprised mostly of a
two-architectures-in-one-port code change?

Regards,

Fred.
