makefile

arm平台上的uclinux系统全部源代码

#
# Makefile for the kernel block device drivers.
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
#
# Note 2! The CFLAGS definition is now inherited from the
# parent makefile.
