# NOTE:
#
# When adding support for a new chip to `esp-hal`, there are a number of
# updates which must be made to the CI workflow in order to reflect this; the
# changes are:
#
# 1.) In the 'esp-hal' job, add the name of the chip to the `matrix.soc` array.
# 1a.) If the device has a low-power core (which is supported in
#      `esp-lp-hal`), then update the `if` condition to build prerequisites.
# 2.) In the 'msrv-riscv' job, add checks as needed for the new chip.
