Greg Ungerer 4a2e130cce m68k: allow ColdFire PCI bus on MMU and non-MMU configuration
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.

Say Y here to enable support for the "DIO" expansion bus used in
HP300 machines. If you are using such a system you almost certainly
want this.

config ZORRO

help
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.

Include support in the kernel for pcmcia on Amiga 1200 and Amiga
600. If you intend to use pcmcia cards say Y; otherwise say N.
config ISA

default y
help
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.
config ATARI_ROM_ISA
bool "Atari ROM port ISA adapter support"
depends on ATARI
help
This option enables support for the ROM port ISA adapter used to
operate ISA cards on Atari. Only 8 bit cards are supported, and
no interrupt lines are connected.
The only driver currently using this adapter is the EtherNEC
driver for RTL8019AS based NE2000 compatible network cards.
