Detailed Description

Parameters passed to RPMessage_init, these are generated via SysCfg.

Note: Set vringTxBaseAddr[], vringTxBaseAddr[] to RPMESSAGE_VRING_ADDR_INVALID for cores that are not needed for IPC RPMessage. You can use RPMessage_Params_init to set valid defaults.; All cores MUST set the same value for vringSize, vringNumBuf, vringMsgSize.; Set vringTxBaseAddr, vringRxBaseAddr, based on source and destination cores.; VRING memory is shared across all cores AND this memory MUST be marked as non-cached at all the cores.
