Hi Wolfgang,
I notice an issues with out of tree builds in current top of tree code: "make O=${SOMEDIR} distclean" leaves files around:
-> rm -fr ${SOMEDIR} -> mkdir -p ${SOMEDIR} -> make -s O=${SOMEDIR} TQM5200S_config Configuring for TQM5200S - Board: TQM5200, Options: TQM5200_B,TQM5200S -> make -s -j8 O=${SOMEDIR} -> find ${SOMEDIR} -type f | wc -l 858 -> make O=${SOMEDIR} distclean CLEAN u-boot.lds include/autoconf.mk include/autoconf.mk.dep CLEAN u-boot.map u-boot.bin u-boot.srec u-boot System.map CLEAN include/config include/generated CLEAN include/config.h include/config.mk -> find ${SOMEDIR} -type f /work/wd/tmp/examples/standalone/interrupt.bin /work/wd/tmp/examples/standalone/interrupt /work/wd/tmp/examples/standalone/sched /work/wd/tmp/examples/standalone/interrupt.srec /work/wd/tmp/examples/standalone/sched.srec /work/wd/tmp/examples/standalone/hello_world.srec /work/wd/tmp/examples/standalone/hello_world.bin /work/wd/tmp/examples/standalone/hello_world /work/wd/tmp/examples/standalone/sched.bin /work/wd/tmp/scripts/basic/fixdep /work/wd/tmp/tools/envcrc /work/wd/tmp/tools/proftool /work/wd/tmp/tools/mkenvimage /work/wd/tmp/tools/mkimage /work/wd/tmp/tools/dumpimage /work/wd/tmp/tools/img2srec /work/wd/tmp/tools/gen_eth_addr /work/wd/tmp/Makefile
I think after a "make O=${SOMEDIR} distclean" the directory ${SOMEDIR} should be really empty (or actually get removed completely).
It seems there are some bugs here. I will fix it in a few days. (Sorry, I am not feeling well today. I've got to go home soon and take a rest.)
Another nice feature that got lost when converting to kbuild is that we used to be able to run just "make <name>" as a shortcut for "make <name_config> ; make all" - this does not work any more.
Or you can "make <name>_config all". Can you live with it?
I am not sure "make <name>" works along with Kconfig. If it is mandatory, we need to do something with it.
