/*
 * The Debug board is designed to function with the P2 Sample, H2
 * Sample and 1610 Innovator boards. The main difference AFAICT is
 * the chip selects used with each system ;
 *
 *   P2 Sample : CS1 of OMAP730 is used to select the CPLD & LAN regs
 *   H2 Sample : CS1a is used to select the CPLD registers.
