+To configure for the current (Rev 3.x) ADS5121
+ make ads5121_config
+This will automatically include PCI, the Real Time CLock, add backup flash
+ability and set the correct frequency and memory configuration.
+
+To configure for the older Rev 2 ADS5121 type (this will not have PCI)
+ make ads5121_rev2_config
