Modification on giet_xml parser and driver:

  • Introducing a new field on the mapping_info header which is used to store the number of IRQ per processor. This number must be declared on the header of all XML description files (irq_per_proc).
  • The number of channels of the ICU/XICU must be equal to the number of processors per cluster multiplied by the number of IRQ per processor (this is verified by the xml_parser).
