payload. Please refer to the "Booting an EL3 payload" section for more
details.
-- ``ENABLE_AMU``: Boolean option to enable Activity Monitor Unit extensions.
- This is an optional architectural feature available on v8.4 onwards. Some
- v8.2 implementations also implement an AMU and this option can be used to
- enable this feature on those systems as well. Default is 0.
-
- ``ENABLE_AMU_AUXILIARY_COUNTERS``: Enables support for AMU auxiliary counters
(also known as group 1 counters). These are implementation-defined counters,
and as such require additional platform configuration. Default is 0.
builds, but this behaviour can be overridden in each platform's Makefile or
in the build command line.
-- ``ENABLE_FEAT_AMUv1``: Numeric value to enable access to the HAFGRTR_EL2
- (Hypervisor Activity Monitors Fine-Grained Read Trap Register) during EL2
- to EL3 context save/restore operations. This flag can take the values 0 to 2,
- to align with the ``FEATURE_DETECTION`` mechanism. It is an optional feature
- available on v8.4 and onwards and must be set to either 1 or 2 alongside
- ``ENABLE_FEAT_FGT``, to access the HAFGRTR_EL2 register.
- Default value is ``0``.

+ and this option can be used to enable this feature on those systems as well.
+ This flag can take the values 0 to 2, the default is 0.
- ``ENABLE_FEAT_AMUv1p1``: Numeric value to enable the ``FEAT_AMUv1p1``
extension. ``FEAT_AMUv1p1`` is an optional feature available on Arm v8.6
