//ody ocmb chips are defined in system device tree. The pdbg targets
//that captures the device path to communicate with system ody ocmb
//chips will be defined in backend device tree.

//ody ocmb system device tree targets need to be mapped to backend
//ody pib device tree targets for communication with the ody ocmb targets.
//Mapping is done based on proc, ocmb chip index of the ody ocmb system target
//with the proc, ocmb index and port number defined in the backend kernel device
//tree

//for get or put scom in kernel mode device path defined in PIBODY will be used
//for cfam device-path specified in HMFSIODY will be used
