# Baremetal image class
#
# This class is meant to be inherited by recipes for baremetal/RTOS applications
# It contains code that would be used by all of them, every recipe just needs to
# override certain variables.
#
# For scalability purposes, code within this class focuses on the "image" wiring
# to satisfy the OpenEmbedded image creation and testing infrastructure.
#
# See meta-skeleton for a working example.
# Toolchain should be baremetal or newlib based.
