io or memory space access enabled. This patch defers the setting
of these bits until after all of the mapping registers are probed.
It might be even better to defer this until a particular mapping
is activated and to disable that type of access when a new
register is activated.
2) The PCI spec is very explicit about how mapping registers and
the expansion ROM mapping register should be probed. This patch
makes cardbus_add_map() follow the spec.
3) The PCI spec allows a device to use the same address decoder for
expansion ROM access as is used for memory mapped register access.
This patch carefully enables and disables ROM access along with
resource (de)activiation.
This doesn't include the prefetching detection stuff (maybe later when code is written to actually turn on prefetching). It also does not use the PCI definitions (yet, I'll try to put this in all at once later)
