$Log: proc_cen_set_inband_addr.C,v $
Revision 1.8 2014/02/05 17:34:30 mfred
Changed include statements to use <> instead of double-quotes.
Revision 1.7 2012/11/30 15:33:50 mfred
Several updates suggested by gerrit code review. Get rid of unused attribute reference. Change name of inband bar attribute.
Revision 1.6 2012/11/15 20:15:01 mfred
Update the hwp to take real address from attribute and modify value for BAR register.
Revision 1.5 2012/11/06 17:11:36 mfred
Procedure now gets the BAR value from the attribute.
Revision 1.4 2012/10/24 15:32:27 mfred
Temporarilly hardcode the BAR value until the attribute is ready.
Revision 1.3 2012/10/11 14:36:24 mfred
Updated code to write to MCS MCFGPR Regsiter.
Revision 1.2 2012/10/10 21:11:15 mfred
Check in some updates to two new procedures.
