U-Boot supports a number of environment variables to pass specific information. The following patches were submitted in the past to one some specific Config.in option to pass some of these variables: - http://patchwork.ozlabs.org/patch/881197/ proposed an option to pass a custom EXT_DTB= variable - http://patchwork.ozlabs.org/patch/1018245/ proposed an option to pass a custom DEVICE_TREE= variable Instead of adding one Config.in option for each of those variables, let's provide a generic mechanism to pass arbitrary variables during U-Boot build step.

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
