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.
