MEMBERS
  signature
	  Contains the string PCIR to uniquely identify the PCI data
	  structure.

  vendor_id
	  Contains the vendor ID as defined in the Vendor ID device register
	  (vendor_id member of pci_config_hdr).

  device_id
	  Contains the device ID as defined in the Device ID device register
	  (device_id member of pci_config_hdr).

  vital_data_off
	  Contains the offset to the vital product data from the start of the
	  ROM image.  PCI Local Bus Specification Revision 2.1 does not
	  define the contents of the vital product data structure.

  struct_len
	  Contains the size (in bytes) of the pci_rom_data data structure.

  struct_rev
	  Identifies the pci_rom_data data structure revision level.  For ROM
	  images compliant with PCI Local Bus Specification Revision 2.1,
	  this member contains the constant PCI_DATA_STRUCT_V2.

  class_code
	  Contains the class code as defined in the Class Code device
	  register (class_code member of pci_config_hdr).

  image_length
	  Contains the length of the image in 512-byte blocks.

  code_revision
	  Contains the revision level of the code in the ROM image.

  code_type
	  Identifies the type of code contained in this section of the ROM.
	  You use the constants INTEL_ROM_CODE_TYPE or OPENFW_ROM_CODE_TYPE
	  in this member. (OPENBOOT_ROM_CODE_TYPE is supported in <pci.h> for
	  backward compatibility; OPENFW_ROM_CODE_TYPE is the preferred
	  symbol.)

  indicator
	  Contains the constant ROM_LAST_IMAGE (bit <7> set) if this is the
	  last image in the ROM.  All other values are reserved.

DESCRIPTION
  The pci_rom_data data structure describes a PCI device's expansion ROM
  image.  The data structure itself is located within the first 64K bytes of
  the ROM image and must be longword aligned.
