   * Macros for Sun2 control space
   */
  
  /*
   * On the Sun3, the 32 bytes of IDPROM are at consecutive addresses in
   * control space starting at 0x00000000.  On the Sun2, the 32 bytes of
   * IDPROM are at offset 8 in each of the the first 32 pages of control
   * space, i.e., on the Sun2, in control space the page frame is used
   * as an index, and the page offset bits are used to select something
   * to use that index with.  I'm not sure which I like better.
