/*
 *      The following must (unless otherwise denoted) have defined for
 * the following modules:
 *
 *      osdStartI2OCp() macro, or,
 *      int _osdStartI2OCp __P((
 *          IN Controller_t   controller,
 *          IN OUT OutGoing_t packet,
 *          IN OUT Callback_t callback));
 *
 *      Optionally osdClockTick(), osdCLOCKTICK,
 *
 *      osdBcopyIn(src_phys,dest,count) and osdBcopyOut(src,dest_phys,count)
 *        macros. osdBcopyIn and osdBcopyOut will be defined locally
 *        utilizing osdVirt definition.
 *
 *      osdBzero(dest,count) macro
 *      osdBcopy(src,dest,count) macro
 *      osdPhys(address) macro
 *
 *      Optionally osdEata4 can be defined to override the default of
 *        osdLocal4 respectively to handle EATA packets sent to us that
 *        are in local format.
 *          #define osdEata4(x) (*(unsigned long __FAR__ *)(x))
 *
 *      Optionally osdEataPack and osdEataUnpack can be defined to deal
 *        with any requirement to handle Virtual addresses that are in
 *        a differing format in the Eata packet than in the local
 *        system. ie:
 *          #define osdEataPack(x) (((((unsigned long)(x))>>12)&0x000FFFF0L) \
 *                             + ((unsigned long)(((unsigned short)(x))&0xF)))
 *        could be used to take a virtual address and put it into the
 *        eata packet format. And
 *          #define osdEataUnpack(x) (((((unsigned long)(x))<<12)&0xFFFF0000L) \
 *                                 + ((unsigned long)(unsigned short)(x)))
 *        could take the address stored in the eata packet and generate
 *        the local virtual address (Segment:Offset). Otherwise, these
 *        are simply passthrough if not defined.
 *
 *      Optionally osdEataVirt and osdEataPhys can be defined to deal
 *        with conversion of Eata addresses from it's format (Physical
 *        or Virtual) to Virtual and Physical respectively. By default
 *        osdEataVirt is defined as osdVirt, and osdEataPhys is
 *        passthrough as it is assumed that the eata packet will be in
 *        a physical form. osdVirtEata is also defined along the same
 *        lines ... Beware of side effects from osdEataVirt and
 *        friends!
 *
 *      Optionally getIrqNum can be defined to point to a local
 *        efficient means of acquiring the IRQ Number. If not defined,
 *        we will create our own version that gets it from the Hardware
 *        Log Page 1 value (which is only correct after FW revision
 *        2036 or later).
 *
 *      Optionally pushInterrupt(), popInterrupt(), disableInterrupt(),
 *        enableInterrupt() semaphore macros or functions.
 *
 *      Optionally define NUM_CALLBACK to set the callback placeholders
 *        as statically placed rather than dynamically allocated
 *        members.
 *
 *      Optionally define NUM_CONTROLLERS to set the LCT cache
 *        statically to some limit (Default to one if not defined) or
 *        to no limit and dynamically allocated if set to -1.
 *
 *      Optionally define NUM_DEVICES to the maximum number of devices
 *        for each controller. Defaults to -1 if NUM_CONTROLLERS is -1,
 *        and to 4*16 if NUM_CONTROLLERS is undefined or set to some
 *        limit.
 *
 *      Optionally define osdAlloc(size) macro to point to memory
 *        allocation mechanism. osdFree(member,size) macro may be
 *        defined for completeness but is not currently used by these
 *        utilities (as we have not placed a requirement to perform
 *        any `new' or `delete' functionality into the eata2i2o
 *        converter). This definition also expands the capability of
 *        the Flash conversion to allow buffering of incoming flash
 *        messages to coalesce them into 64KB writes to the adapter
 *        (required since the fifth generation controllers erase and
 *        write in up to 64KB blocks).
