- Produces the Legacy Region Protocol.
-
- This generic implementation of the Legacy Region Protocol does not actually
- perform any lock/unlock operations. This module may be used on platforms
- that do not provide HW locking of the legacy memory regions. It can also
- be used as a template driver for implementing the Legacy Region Protocol on
- a platform that does support HW locking of the legacy memory regions.
