help
Optimize the stepper code for Trinamic stepper motor drivers
that are configured in UART or SPI mode (and thus can perform
a step on both "edges" of the step pin). Enabling this option
typically improves the stepper cpu performance by about 20%
when using these drivers. If this option is disabled the code
will instead deploy optimizations that improve the cpu
performance by about 20% for traditional drivers (those that
take a step only on the "rising" or "falling" level of the
step pin).

config INITIAL_PINS

depends on LOW_LEVEL_OPTIONS
help
One may specify a comma separated list of gpio pins to set
during the micro-controller startup sequence. By default the
pins will be set to output high - preface a pin with a '!'
character to set that pin to output low.
# The HAVE_x options allow boards to disable support for some commands
# if the hardware does not support the feature.
