 Secure interrupt configuration are specified in an 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:

 CPU drivers that apply errata workaround can optionally implement an assembly
 function that report the status of errata workarounds pertaining to that CPU.

+For a driver that registers the CPU, for example, ``cpux`` via ``declare_cpu_ops``
 macro, the errata reporting function, if it exists, must be named
 ``cpux_errata_report``. This function will always be called with MMU enabled; it
 must follow AAPCS and may use stack.
