Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de admittedly, this is more a kernel Kbuild question, but in common/Makefile, i see the snippet: extra-$(CONFIG_ENV_IS_EMBEDDED) += env_embedded.o obj-$(CONFIG_ENV_IS_IN_EEPROM) += env_embedded.o extra-$(CONFIG_ENV_IS_IN_FLASH) += env_embedded.o what is the functional difference between using "extra-" and "obj-" in the above? those three lines look ... inconsistent? anyway, what is going on there? thanks. rday -- ======================================================================== Robert P.
