/*******************************************************************************
 * This structure describes some of the implementation defined attributes of the
 * GICv3 IP. It is used by the platform port to specify these attributes in order
 * to initialise the GICV3 driver. The attributes are described below.
 *
 * 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 '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.
 *
 * 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.
 *
 * 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_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 '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.
