  14  * bridge.h - header file for bridge chip and bridge portion of xbridge chip
  15  *
  16  * Also including offsets for unique PIC registers.
  17  * The PIC asic is a follow-on to Xbridge and most of its registers are
  18  * identical to those of Xbridge.  PIC is different than Xbridge in that
  19  * it will accept 64 bit register access and that, in some cases, data
  20  * is kept in bits 63:32.   PIC registers that are identical to Xbridge
  21  * may be accessed identically to the Xbridge registers, allowing for lots
  22  * of code reuse.  Here are the access rules as described in the PIC
  23  * manual:
  24  *
  25  *      o Read a word on a DW boundary returns D31:00 of reg.
  26  *      o Read a DW on a DW boundary returns D63:00 of reg.
  27  *      o Write a word on a DW boundary loads D31:00 of reg.
  28  *      o Write a DW on a DW boundary loads D63:00 of reg.
  29  *      o No support for word boundary access that is not double word
  30  *           aligned.
  31  *
  32  * So we can reuse a lot of bridge_s for PIC.  In bridge_s are included
  33  * #define tags and unions for 64 bit access to PIC registers.
  34  * For a detailed PIC register layout see pic.h.
