From 8813d1c00ca923c1683da625ff85959be1db9a49 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 9 May 2007 02:33:30 -0700 Subject: mca: add integrated device bus matching The MCA bus has a few "integrated" functions, which are effectively virtual slots on the bus. The problem is that these special functions don't have dedicated pos IDs, so we have to manufacture ids for them outside the pos space ... and these ids can't be matched by the standard matching function, so add a special registration that requests a list of pos ids or a particular integrated function.
