This series adds support to skip powering up of trace unit on systems with an errata which stops CPU watchdog counter when power up bit is set (TRCPDCR.PU = 1). Setting this bit is not required on Qualcomm Technologies Inc. chipsets where this errata exists since the ETMs are in the same power domain as their respective CPU cores.
