Gerwin Klein 24c0c5c390 spec+proof: use generated config constants 
This includes replacing previous ASpec names for such constants with
the names used in Haskell/ExecSpec to avoid duplication. This also
makes some of the proofs slightly more generic.

CapDL Refinement Proof

This proof establishes that seL4's abstract specification is a formal refinement (i.e. a correct implementation) of its capDL specification. It is described as part of an ICFEM '13 paper.

Building

To build from the l4v/ directory, run:

./isabelle/bin/isabelle build -d . -v -b DRefine

Important Theories

The top-level theory where the refinement statement is established over the entire kernel is Refine_D; the state-relation that relates the state-spaces of the two specifications is defined in StateTranslation_D and the basic correspondence property proved over each kernel function is defined in Corres_D.
