# Before including this Makefile, you should specify the following variables
# in your Makefile:
# - INCLCMNDIR : Points to the common include directory
# - INCLCMNDIR : Points to the board specific include directory
# - SLOFCMNDIR : Points to the common SLOF directory
# - SLOFBRDDIR : Points to the board specific SLOF directory
# - LLFWCMNDIR : Points to the common LLFW directory
# - LLFWBRDDIR : Points to the board specific LLFW directory

# Set LLFW directories (should normally be set from parent Makefile):
TOPBRDDIR ?= $(shell cd .. && pwd)
LLFWBRDDIR ?= $(TOPBRDDIR)/llfw
LLFWCMNDIR ?= $(SLOFCMNDIR:%/slof=%/llfw)
