I'm still leaving out CONFIG_CORESIGHT_SOURCE_ETM4X because it depends on the outcome of the investigation into CONFIG_PID_IN_CONTEXTIDR, but I think we should enable these ones for now and start getting some of the benefits sooner.
Changes since v1:
* Remove CONFIG_CORESIGHT_CTI_INTEGRATION_REGS=y which shouldn't be enabled by default
-----
As suggested by Catalin here's the change to add Coresight to defconfig.
Unfortunately I don't think we should add CONFIG_CORESIGHT_SOURCE_ETM4X which builds a few files until [1] is merged because of the overhead of CONFIG_PID_IN_CONTEXTIDR.
