Up to now we have only had support for the PCI bus when running the ColdFire CPU family with the MMU enabled. The only reason for this was the incomplete state of the IO remapping and access functions when running with the MMU disabled. Recent fixes and improvements to the ColdFire IO access code means we can now support the PCI bus when running non-MMU enabled as well. So modify the configuration support to allow it to be selected no matter what choice of MMU mode is used.

This enables support for the Zorro bus in the Amiga. If you have
|
|
expansion cards in your Amiga that conform to the Amiga
|
|
AutoConfig(tm) specification, say Y, otherwise N. Note that even
|
|
expansion cards that do not fit in the Zorro slots but fit in e.g.
|
|
the CPU slot may fall in this category, so you have to say Y to let
|
|
Linux use these.

Find out whether you have ISA slots on your motherboard. ISA is the
|
|
name of a bus system, i.e. the way the CPU talks to the other stuff
|
|
inside your box. Other bus systems are PCI, EISA, MicroChannel
|
|
(MCA) or VESA. ISA is an older system, now being displaced by PCI;
|
|
newer boards don't support it. If you have ISA, say Y, otherwise N.

This option enables support for the ROM port ISA adapter used to
