    The recipes-bsp layer contains hardware specific recipes for u-boot and radio configuration. The radio directories (calibrator, ti-bt-firmware, ublox-eeprom-parser) should not be altered as they are a part of the regulatory compliance. Any modification to these layers might void the u-blox warranty and breaks the regulatory requirements.
