+ *
+ * The Db1000 is used as a reference:  Per-socket card-, carddetect- and
+ *  statuschange IRQs connected to SoC GPIOs, control and status register
+ *  bits arranged in per-socket groups in an external PLD.  All boards
+ *  listed here use this layout, including bit positions and meanings.
+ *  Of course there are exceptions in later boards:
+ *
+ *	- Pb1100/Pb1500:  single socket only; voltage key bits VS are
+ *			  at STATUS[5:4] (instead of STATUS[1:0]).
+ *	- Au1200-based:	  additional card-eject irqs, irqs not gpios!
