The ASWG ECR 2303 introduces a new field 'TRBE
interrupt' to GICC structure in ACPI 6.5.
The Trace Buffer Extension (TRBE) interrupt is a
Processor Private interrupt (PPI) and is used to
specify a platform-specific interrupt to signal
TRBE events.

When TRBE is enabled the FVP model uses the PPI 15
(i.e. INT ID 31) as the TRBE interrupt.

Therefore, check the debug feature register
ID_AA64DFR0_EL1.TraceBuffer field to see if TRBE is
enabled
When ETE is enabled in the FVP model the firmware can check
the debug feature register ID_AA64DFR0_EL1.TraceVer field
to identify the presence of FEAT_ETE and add an ETE device
to the CPU node in the AML CPU hierarchy. This enables the
Operating System driver to probe and enable ETE support.

Hello
I agree with you on the problem statement.
But I don't think this is a desired solution.
We expect Platform BDS to call the PhysicalPresenceLib. As such, why not clear
