+ * This file provides support for the ngPIXIS, a board-specific FPGA used on

+ *
+ * A "switch" is black rectangular block on the motherboard. It contains
+ * eight "bits". The ngPIXIS has a set of memory-mapped registers (SWx) that
+ * shadow the actual physical switches. There is also another set of
+ * registers (ENx) that tell the ngPIXIS which bits of SWx should actually be
+ * used to override the values of the bits in the physical switches.
+ *
+ * The following macros need to be defined:
+ *
+ * PIXIS_BASE - The virtual address of the base of the PIXIS register map
+ *
+ * PIXIS_LBMAP_SWITCH - The switch number (i.e. the "x" in "SWx"). This value
+ * is used in the PIXIS_SW() macro to determine which offset in
+ * the PIXIS register map corresponds to the physical switch that controls
+ * the boot bank.
+ *
+ * PIXIS_LBMAP_MASK - A bit mask the defines which bits in SWx to use.
+ *
+ * PIXIS_LBMAP_SHIFT - The shift value that corresponds to PIXIS_LBMAP_MASK.
+ *
+ * PIXIS_LBMAP_ALTBANK - The value to program into SWx to tell the ngPIXIS to
+ * boot from the alternate bank.
