The original UBOOT_FIXUP_LIBFDT_INCLUDE hook only works for u-boot versions starting from v2017.11. As older u-boot versions are still in common use today, e.g. in the ci20_defconfig, extend the hook to cover a wider range of u-boot versions. The main code change was proposed by Arnout Vandecappelle in [1]. Testing and comment changes were done by Thomas De Schampheleire. Additional (build) testing done by Yann. [1] http://lists.busybox.net/pipermail/buildroot/2019-May/251231.html This was tested with the following defconfigs, that each excercise one case: ----.-- No defconfig identified 2010.06 'lib/libfdt/', used to be simply 'libfdt' before upstream commit 0de71d507157... 2013.10 ci20_defconfig 2014.04 'srctree' used to be called 'SRCTREE' before upstream commit 01286329b27b27ea... 2017.05 olimex_a13_olinuxino_defconfig 2017.11 scripts/dtc/libfdt only exists since upstream commit c0e032e0090d6541549b19cc... 2018.01 mx6udoo_defconfig 2018.03 core change is equivalent to upstream commit e0d20dc1521e74b82dbd69be53a04884... 2019.10 nanopi_neo_defconfig Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com> [yann.morin.1998@free.fr: add the build-test results] Signed-off-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
