MdePkg: MADT: Add Online capable flag in GICC
Bugzilla: 3706 'Code First - MADT GICC new flags'
On ARM systems physical CPU hotplug is not supported.
All CPUs are considered present and this is true
throughout the system uptime.
The ECR 2285 introduces a new 'online-capable' flag
in the GICC structure flags in ACPI 6.5, to signal
firmware policy (CPU is not enabled but it can be
enabled and onlined). This enables OSPM to support
virtual CPU hotplug (on virtual platforms for
instance).
This ECR also updates the MADT table revision to 6
to reflect the ACPI 6.5 changes. Therefore, update
the MADT table revision to match the value as
specified in ACPI 6.5.

MdePkg: MADT: Add TRBE interrupt to GICC
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.

DynamicTablesPkg: Update MADT generator for ACPI 6.5
The ACPI 6.5 specification updates the MADT table to add
a new field to GICC for specifying the TRBE interrupt and
also adds support for Online Capable flag to the GICC flags.
The Online Capable flags should be passed transparently
through as specified in the CM_ARM_GICC_INFO.Flags field
and only require the MADT table revision to be setup to
6 to reflect the ACPI 6.5 specification.
The TRBE field needs to be appropriately setup in the
GICC structure.
Therefore, update the MADT generator to reflect the
above updates required for supporting ACPI 6.5

used to provide information about Embedded Trace

available on a platform.
Although ETE and ETM share the same HID,
ETE has a system register interfaces, unlike
ETM which requires memory mapped registers.
Since this patch aims to support ETE it does
not describe any memory mapped registers.
However, required support for ETM can be added

DynamicTablesPkg: Add ETE device to CPU node in AML
The Coresight Embedded Trace Extension (ETE) feature
can be detected by the platform firmware by examining
the debug feature register ID_AA64DFR0_EL1.TraceVer
field.
The platform configuration manager can then describe
the ETE by creating CM_ARM_ET_INFO object(s) and
referencing these in CM_ARM_GICC_INFO.EtToken.
The 'Table 3: Compatible IDs for architected
CoreSight components' in the 'ACPI for CoreSight
1.2 Platform Design Document' specifies the HID
value for Coresight ETE and CoreSight Embedded
Trace Macrocell (ETM) v4.x as ARMH C500.
Therefore, update the SsdtCpuTopologyGenerator
to add an ETE device to the CPU node in the AML
CPU hierarchy so that an OS can utilise this
information.
Note: Although ETE and ETM share the same HID,
ETE has a system register interfaces, unlike
ETM which requires memory mapped registers.
Since this patch aims to support ETE, the AML
description does not describe any memory mapped
registers. However, support for ETM can be
added in the future.
