This fixes multipchip rainier boot issue. for Rainer: chip0: ibm,primary-topology-index = < 0x0>; chip1: ibm,primary-topology-index = < 0x4>; chip2: ibm,primary-topology-index = < 0x8>; chip3: ibm,primary-topology-index = < 0xc>; for Denali: node0: chip0: ibm,primary-topology-index = < 0x0>; chip1: ibm,primary-topology-index = < 0x1>; chip2: ibm,primary-topology-index = < 0x2>; chip3: ibm,primary-topology-index = < 0x3>; node1: chip0: ibm,primary-topology-index = < 0x4>; chip1: ibm,primary-topology-index = < 0x5>; chip2: ibm,primary-topology-index = < 0x6>; chip3: ibm,primary-topology-index = < 0x7>; Note that bmc_create_node() gets called very early in the boot process. Hence we have to traverse through HDAT ntuple to get right topology index. May be we can optimize pcid_to_topology_idx() function as its pretty much duplicate of pcid_to_chip_id(). But for now lets keep it as separate function.
