# adjust config if synthesizing with any modifications
# This code is subtle with ifneq. It successively turns off a larger
# set of features in order of cycle time limiting.
# When mod = orig, all features are ON
# When mod = PMP0, the number of PMP entries is set to 0
# when mod = noPriv, the privileged unit and PMP are disabled
# when mod = noFPU, the FPU, privileged unit, and PMP are disabled
# when mod = noMulDiv, the MDU, FPU, privileged unit, and PMP are disabled.
