/* Please note: ZorroIII implementation seems to work different

* address is 0xff000000 while the ZorroII config space starts
* at 0x00e80000. In reality, both, Z2 and Z3 cards are
* configured in the ZorroII config space. Kickstart 3.1 doesn't
* even do a single read or write access to the ZorroIII space.
* The original Amiga include files tell the same as the HRM.
* ZorroIII: If you set ext_size in er_Flags and give a Z2-size
* in er_Type you can very likely add some ZorroII address space
* to a ZorroIII card on a real Amiga. This is not implemented
* yet.
* -- Stefan
*
* Surprising that 0xFF000000 isn't used. Maybe it depends on the
* ROM. Anyway, the HRM says that Z3 cards may appear in Z2 config
* space, so what we are doing here is correct.
