## Android Makefile for kernel module
## by Kirby.Wu, 20090729, mediatek.inc
##
## this android makefile is (currently) used to build all kernel modules 
## and put them into android platform output directory. 
##
## to build kernel modules into system.img,
##   config build/target/board/<target>/BoardConfig.mk:
##     KERNEL_CONFIG_FILE := <your desired config file> # use .config if omit
##     TARGET_MODULES     := true                       # do make modules
##
