// 1.6 03/10/14 jmcgill Add endpoint power up
// 1.5 11/08/13 jmcgill Updates for RAS review
// 1.4 02/18/13 thomsen Changed targeting to use Abus_chiplet,
// chip, connected_Abus_chiplet &
// connected_chip to match Xbus and DMI
// target list so they are common
// 1.3 02/10/13 jmcgill Leverage chiplet level targeting, invoke
// custom initfile
// 1.2 01/20/13 jmcgill Add consistency check for A chiplet
// partial good support
