Synchronize the coresight code of the Linux mainline to support ETE tracing
Add support for ETE tracing
Add ETE as one of the supported device types we support
with ETM4x driver. The devices are named following the
existing convention as ete.
Add TRBE driver
TRBE always needs to be used along with it's corresponding percpu ETE
component. ETE generates trace data which is then captured with TRBE.
Unlike traditional sink devices, TRBE is a CPU feature accessible via
system registers. But it's explicit dependency with trace unit (ETE)
requires it to be plugged in as a coresight sink device.
Add TMC driver
It can present itself as an ETF (Embedded Trace FIFO) or ETR
(Embedded Trace Router).
ETF configured in HW fifo mode it acts as link.
ETR always acts as a sink and can be used to route data to memory
allocated in RAM.
