#ifndef __PNOR_HIOMAPDD_H
#define __PNOR_HIOMAPDD_H
/*
* The PnorHiomapDD class implements fallback semantics for the HIOMAP
* transport implementations (currently, AST mailbox and IPMI). The constructor
* probes each transport, preferring IPMI over the mailbox. If a transport's
* probe is successful the instance of the transport's class is stored in
* the iv_pnor member of PnorHiomapDD.
*
* With this in place, we register the readFlash() and writeFlash() methods
* of PnorHiomapDD as the handlers for the PNOR device driver route. Each
* method then delegates to the respective method on the instance of the class
* of transport that was successfully probed.
