2021-11-26	coresight: configuration: Update API to introduce load owner concept	Mike Leach	1	-2/+7
	Update the existing load API to introduce a "load owner" concept. This allows the tracking of the loaded configurations and features against the loading owner type, to allow later unload according to owner. A list of loaded configurations by owner is created. The load owner infrastructure will be used in following patches to implement dynanic load and unload, alongside dependency tracking.

2021-08-18	coresight: config: Add preloaded configurations	Mike Leach	1	-0/+31
	Preload set of configurations. This patch creates a small set of preloaded configurations and features that are available immediately after coresight has been initialised. The current set provides a strobing feature for ETMv4, that creates a periodic sampling of trace by switching trace generation on and off using counters in the ETM. A configuration called "autofdo" is also provided that uses the 'strobing' feature and provides a couple of preset values, selectable on the perf command line.
