Introduction of TPDM CMB(Continuous Multi Bit) subunit CMB subunit is responsible for creating a dataset element, and is also optionally responsible for packing it to fit multiple elements on a single ATB transfer if possible in the configuration. The TPDM Core Datapath requests timestamps be stored by the TPDA and then delivering ATB sized data (depending on ATB width and element size, this could be smaller or larger than a dataset element) to the ATB Mast FSM. The CMB makes trace elements in two modes. In �continuous� mode, every valid data cycle creates an element. In �trace on change� mode, when valid data changes on the bus, a trace element is created. In continuous mode, all cycles where this condition is true create trace elements. In trace on change mode, a data element is only when the previously sampled input is different from the current sampled input. The CMB subunit must be configured prior to enablement. This series adds support for TPDM to configure the configure CMB subunit.
Please base your next version on for-next/queue branch on the coresight repository. Suzuki
