Make firmware download logic more generic to cope with Lucent/Agere
cards as well.
Add programming initialisation and termination functions.
Extra algorithm to program PDA values, including using default values.
Ensure PDA read is terminated.
Turn off aux stuff when finished.
Option to program in limited block sizes (controlled by macro).
Option to read PDA from EEPROM.
