* 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.
