I'm aware of the make config/menuconfig/xconfig etc., but a program I am writing for Uni will require that I am able to directly configure the Makefile(s)... Can anyone give me a general overview of where all the CONFIG_blah_blah_blahs go? I had a look at the Makefile, but it wasn't very instructive. For example, in drivers/net/Makefile: . . . ifeq($(CONFIG_NE2000),y) L_OBJS += ne.o . . . Where does CONFIG_NE2000 get defined? I'd appreciate it if someone could tell me the general rule. Thanks
