modification history
--------------------
01g,15apr99,srr  Changed to WRS address space naming convention.
01f,09feb99,dmw  Add timer inhibit define MPIC_TIMER_BASE_CT_CI.
01e,14apr98,ms_  merged Motorola mv2700 support
01d,11feb98,tb   Added TAS support which uses VMEbus RMW
01c,29apr97,dat  replaced pci.h with pciIomapLib.h
01b,23apr97,mas  merged with sl82565IntrCtl.h (SPR 8170).
01a,30oct96,rhk  created by Motorola.
