# The following parameter changes the default programmer that will be used if there is no -p/--programmer
# argument given when running flashrom. The predefined setting does not enable any default so that every
# user has to declare the programmer he wants to use on every run. The rationale for this to be not set
# (to e.g. the internal programmer) is that forgetting to specify this when working with another programmer
# easily puts the system attached to the default programmer at risk (e.g. you want to flash coreboot to another
# system attached to an external programmer while the default programmer is set to the internal programmer, and
# you forget to use the -p parameter. This would (try to) overwrite the existing firmware of the computer
# running flashrom). Please do not enable this without thinking about the possible consequences. Possible
