This is the latest release tag in the Xilinx repository, based on U-Boot v2016.01 in the mainline. Commit46d6a561be("zedboard: Generate BOOT.BIN automatically") switched from the Xilinx GitHub repository to the U-Boot mainline, but this commit gets it back to the Xilinx GitHub repository for the following reasons: - This defconfig still relies on the Xilinx's local repository for the kernel. The vendor does the best test for the combination of U-Boot and the kernel with the same release tag (xilinx-v2016.2 in this case). - At the time of commit46d6a561be, the u-boot-xlnx still needed manual copy of ps7_init(_gpl).c/h in order to build a working SPL image. So, the mainline U-Boot had advantage in that point of time. However, the improvement in the mainline U-Boot was merged into the u-boot-xlnx at the xilinx-v2015.3 release. Now, the mainline and the u-boot-xlnx are even in this point of view. - The mainline U-Boot defaults to boot FIT, so something must be done; either patch environments around with a local patch to switch to uImage booting (current solution), or build an FIT with a post build script (chromebook snow does this). On the other hand, the Xilinx repository defaults to uImage booting, so it is straightforward, and needs no addition care. This commit does: - Switch to the Xilinx custom git repository, and stick to the xilinx-v2016.2 tag. - Delete the local patch board/avnet/zedboard/uboot/0001... since the Xilinx custom repository can boot uImage by default. - Enable BR2_TARGET_UBOOT_FORMAT_IMG instead of ..._FORMAT_DTB_IMG since all the Zynq boards in U-Boot enable CONFIG_OF_EMBED. - Replace BR2_TARGET_UBOOT_ZYNQ_IMAGE with BR2_TARGET_UBOOT_SPL_NAME since U-Boot can natively generate the Zynq boot image now. The Zynq image support for mkimage tool was upstreamed at v2016.01 (so xilinx-v2016.1 as well), so no additional tool is needed any more. - Update readme.txt Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Matt Weber <matthew.weber@rockwellcollins.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.
