# The ksdk uses the CPU name to expose SOC-specific features of a given
# peripheral. For example, the UART peripheral may be instantiated with/without
# a hardware FIFO, and the size of that FIFO may be different for each instance
# in a given SOC. See fsl_device_registers.h and $(KSDK_DEVICE)_features.h

# Soon we will add support here to build the CMSIS-CORE system configuration
# object using the ksdk device name. For example:
# obj-y += devices/$(KSDK_DEVICE)/system_$(KSDK_DEVICE).o
#
# Although it is not normal Kbuild practice, drilling down like this avoids the
# need for repetitive Makefiles for every ksdk device.
