Help: ICE_FLAGS_GPSMODE=MODE

Sets non-standard behavior of the GPS module.

Sets non-standard behavior of the GPS module.
  mode=0 - enable 10MHz reference without GPS training or 1PPS output
  mode=1 - enable 10MHz reference, GPS training, 1PPS output and IRIG-B (def)
  mode=2 - enhanced mode for platforms in motion

The mode selection changes the defaults for the GPSOPTS flag.  To set mode=0 and 
still put out a sloppy 1PPS use the combined flags:  GPSMODE=0|GPSOPTS=(-NPPS).

It should be specified in the card definition alias if at all possible.
Normally, the GPS module is not reset during a typical card reset or FORCE=1 reset.
To change this flag value after the card is up and running, you must add the flag FORCE=2 
and issue a reset.
