EEPROM init table
- The defaults 'feature bits' set in statemachine.h are basically ignored (6-28-09). Although loaded in sm_init.c, they're overwritten in demux_sm - where it reads the the EEPROM init table.
- if FEATURE_MC_CURRENT_UPDATES is NOT SET, then demux_sm skips the states that boot MC through mode 2
- if FEATURE_USE_IMU is set, then after MC is boot (immediately before RUN_TIME), the dataport_select is set to two, and the IMU communications is enabled.
Problems / Goals
- need to be able to cleanly specify to boot too.
- great a global called 'run_level'. Each thing that gets turned on has a minimum level.
- what if a 'needed' table isn't loaded - eg calibration table.
- possibly this type of error should limit the maximum level of boot capability. eg no calb table, then at most we remain in a mode that will allow for calibration
