+Configuring secure interrupts
+-----------------------------
+
+The GIC driver is responsible for performing initial configuration of secure
+interrupts on the platform. To this end, the platform is expected to provide the
+GIC driver (either GICv2 or GICv3, as selected by the platform) with the
+interrupt configuration during the driver initialisation.
+
+There are two ways to specify secure interrupt configuration:
+
+#. Array of secure interrupt properties: In this scheme, in both GICv2 and GICv3
+ driver data structures, the ``interrupt_props`` member points to an array of
+ interrupt properties. Each element of the array specifies the interrupt
+ number and its configuration, viz. priority, group, configuration. Each
+ element of the array shall be populated by the macro ``INTR_PROP_DESC()``.
+ The macro takes the following arguments:
+
+ - 10-bit interrupt number,
+
+ - 8-bit interrupt priority,
+
+ - Interrupt type (one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1``,
+ ``INTR_TYPE_NS``),
+
+ - Interrupt configuration (either ``GIC_INTR_CFG_LEVEL`` or
+ ``GIC_INTR_CFG_EDGE``).
+
+#. Array of secure interrupts: In this scheme, the GIC driver is provided an
+ array of secure interrupt numbers. The GIC driver, at the time of
+ initialisation, iterates through the array and assigns each interrupt
+ the appropriate group.
+
+ - For the GICv2 driver, in ``gicv2_driver_data`` structure, the
+ ``g0_interrupt_array`` member of the should point to the array of
+ interrupts to be assigned to *Group 0*, and the ``g0_interrupt_num``
+ member of the should be set to the number of interrupts in the array.
+
+ - For the GICv3 driver, in ``gicv3_driver_data`` structure:
+
+ - The ``g0_interrupt_array`` member of the should point to the array of
+ interrupts to be assigned to *Group 0*, and the ``g0_interrupt_num``
+ member of the should be set to the number of interrupts in the array.
+
+ - The ``g1s_interrupt_array`` member of the should point to the array of
+ interrupts to be assigned to *Group 1 Secure*, and the
+ ``g1s_interrupt_num`` member of the should be set to the number of
+ interrupts in the array.
+
+ **Note that this scheme is deprecated.**

*
- * 1. The 'gicd_base' field contains the base address of the Distributor
- * interface programmer's view.
+ * The 'gicd_base' field contains the base address of the Distributor interface
+ * programmer's view.
+ *
+ * The 'gicr_base' field contains the base address of the Re-distributor
+ * interface programmer's view.
+ *
+ * The 'g0_interrupt_array' field is a pointer to an array in which each entry
+ * corresponds to an ID of a Group 0 interrupt. This field is ignored when
+ * 'interrupt_props' field is used. This field is deprecated.
*
- * 2. The 'gicr_base' field contains the base address of the Re-distributor
- * interface programmer's view.
+ * The 'g0_interrupt_num' field contains the number of entries in the
+ * 'g0_interrupt_array'. This field is ignored when 'interrupt_props' field is
+ * used. This field is deprecated.
*
- * 3. The 'g0_interrupt_array' field is a ponter to an array in which each
- * entry corresponds to an ID of a Group 0 interrupt.
+ * The 'g1s_interrupt_array' field is a pointer to an array in which each entry
+ * corresponds to an ID of a Group 1 interrupt. This field is ignored when
+ * 'interrupt_props' field is used. This field is deprecated.
*
- * 4. The 'g0_interrupt_num' field contains the number of entries in the
- * 'g0_interrupt_array'.
+ * The 'g1s_interrupt_num' field contains the number of entries in the
+ * 'g1s_interrupt_array'. This field must be 0 if 'interrupt_props' field is
+ * used. This field is ignored when 'interrupt_props' field is used. This field
+ * is deprecated.
*
- * 5. The 'g1s_interrupt_array' field is a ponter to an array in which each
- * entry corresponds to an ID of a Group 1 interrupt.
+ * The 'interrupt_props' field is a pointer to an array that enumerates secure
+ * interrupts and their properties. If this field is not NULL, both
+ * 'g0_interrupt_array' and 'g1s_interrupt_array' fields are ignored.
*
- * 6. The 'g1s_interrupt_num' field contains the number of entries in the
- * 'g1s_interrupt_array'.
+ * The 'interrupt_props_num' field contains the number of entries in the
+ * 'interrupt_props' array. If this field is non-zero, both 'g0_interrupt_num'
+ * and 'g1s_interrupt_num' are ignored.
*
- * 7. The 'rdistif_num' field contains the number of Redistributor interfaces
- * the GIC implements. This is equal to the number of CPUs or CPU interfaces
- * instantiated in the GIC.
+ * The 'rdistif_num' field contains the number of Redistributor interfaces the
+ * GIC implements. This is equal to the number of CPUs or CPU interfaces
+ * instantiated in the GIC.
*
- * 8. The 'rdistif_base_addrs' field is a pointer to an array that has an entry
- * for storing the base address of the Redistributor interface frame of each
- * CPU in the system. The size of the array = 'rdistif_num'. The base
- * addresses are detected during driver initialisation.
+ * The 'rdistif_base_addrs' field is a pointer to an array that has an entry for
+ * storing the base address of the Redistributor interface frame of each CPU in
+ * the system. The size of the array = 'rdistif_num'. The base addresses are
+ * detected during driver initialisation.
*
- * 9. The 'mpidr_to_core_pos' field is a pointer to a hash function which the
- * driver will use to convert an MPIDR value to a linear core index. This
- * index will be used for accessing the 'rdistif_base_addrs' array. This is
- * an optional field. A GICv3 implementation maps each MPIDR to a linear core
- * index as well. This mapping can be found by reading the "Affinity Value"
- * and "Processor Number" fields in the GICR_TYPER. It is IMP. DEF. if the
- * "Processor Numbers" are suitable to index into an array to access core
- * specific information. If this not the case, the platform port must provide
- * a hash function. Otherwise, the "Processor Number" field will be used to
- * access the array elements.
