modification history 
-------------------- 
01g,03feb00,rhv  Making pciAutoIoAlloc, pciAutoMemAlloc and pciAutoIntAssign 
                 externally callable. 
01f,07may99,tm   Added pciAutoAddrAlign to perform alignment checking 
                 pciAutoFuncDis-/En-able, pciAutoRegConfig public (SPR 26484) 
01e,30mar99,dat  SPR 25312, changed class to pciClass 
01d,29jul98,scb  added roll call capability 
01c,29jul98,tm   code review changes / added _DEV_DISPLAY attribute 
01b,24jul98,tm   added int routing offset to PCI_LOC structure  
                 added autoIntRouting boolean to PCI_SYSTEM structure 
		 added protos for pciAutoBusNumberSet, pciAutoDevReset 
01a,19feb98,dat  written, from Motorola.
