+ * TF-A supports many Arm architectural features starting from arch version
+ * (8.0 till 8.7+). These features are mostly enabled through build flags. This
+ * mechanism helps in validating these build flags in the early boot phase
+ * either in BL1 or BL31 depending on the platform and assists in identifying
+ * and notifying the features which are enabled but not supported by the PE.
+ *
+ * It reads all the enabled features ID-registers and ensures the features
+ * are supported by the PE.
+ * In case if they aren't it stops booting at an early phase and logs the error
+ * messages, notifying the platforms about the features that are not supported.
+ *
+ * Further the procedure is implemented with a tri-state approach for each feature:
+ * ENABLE_FEAT_xxx = 0 : The feature is disabled statically at compile time
+ * ENABLE_FEAT_xxx = 1 : The feature is enabled and must be present in hardware.
+ *                       There will be panic if feature is not present at cold boot.
+ * ENABLE_FEAT_xxx = 2 : The feature is enabled but dynamically enabled at runtime
+ *                       depending on hardware capability.
+ *
+ * For better readability, state values are defined with macros namely:
+ * { FEAT_STATE_0, FEAT_STATE_1, FEAT_STATE_2 } taking values as their naming.
