/* Compile time check to test structure size has not changed *
Changing the size of one of the eeprom structs may cause wrong data to
be loaded. Error out if the struct size changes.
This function tries not avoid checking or using the defines
other than the CPU arch and board type so changes in other
defines also trigger the struct size changes */
