* Initialize PCIC_INTR and PCIC_CSC_INTR on all chips, not just TI.
* Leave card detect interrupts enabled in PCIC_CSC_INTR. (This requires
reading PCIC_CSC in the interrupt handler on some chips, so do that too.)
* Leave PCIC_INTR_ENABLE set, as some chips require this to post card detect
interrupts while in PCMCIA mode.
* Leave PCIC_INTR_RESET (which is inverted) set at all times *except* when
powering up a socket, as some chips will use it to drive RESET# low even
while a CardBus card is in the slot.
This makes PCMCIA and CardBus cards works with some TI chips. Cross-checked
with a Toshiba ToPIC 95B.

This directory contains files which are used during PCI configuration
and PCI device drivers. Eventually, most of the device drivers and
some of the configuration support should become machine-independent
and be moved to a more general location.
The configuration support was implemented according to the `PCI Local
Bus Specification, Production Version, Revision 2.0' dated April 30,
1993. Section numbers referred to in the code may be specific to that
edition of the specification.
Some attempt has been made to insure that the code works on rogue
machines where the BIOS doesn't do its job, but in general I can't
guarantee that.
