![]() [ Upstream commit 4ff6039ffb79a4a8a44b63810a8a2f2b43264856 ]
As recommended by section 4.3.7 ("Synchronization when using system
instructions to progrom the trace unit") of ARM IHI 0064H.b, the
self-hosted trace analyzer must perform a Context synchronization
event between writing to the TRCPRGCTLR and reading the TRCSTATR.
Additionally, add an ISB between the each read of TRCSTATR on
coresight_timeout() when using system instructions to program the
trace unit.
