# This makefile is for "local" compilation, that is compiling a driver without using the standard Linux way (make Xconfig etc...)
# Anyway to compile this driver you need to have a already configured Linux kernel source tree

# This makefile allows to build the driver outside the kernel
# you need then to specify where are located the kernel source the includes used by this driver

# Notes:
# * the source of these drivers are generally located in the kernel source directory
# in the path $(TOPDIR)/drivers/addidata/
# * the the ADDI-DATA specific includes are generally located in the kernel source directory
# in the path $(TOPDIR)/include/linux/addidata
