Kind of. I hope it will be solved in a long run. In U-Boot, ARCH, VENDOR, BOARD directories are still treated specially for some historical reason. Board directory is selected like follows: libs-y += $(if $(BOARDDIR),board/$(BOARDDIR)/) and it has made it difficult to descend into board/ by "make clean" because "make clean" should not expect the existing .config file. If we could completely switched to "obj-$(CONFIG_FOO)" style in the future, this problem would go away. We need more effort to achieve this. > Should make descend > into the board directory?

Sorry, I cannot suggest a good solution now. -- Best Regards Masahiro Yamada _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
