Because uboot requires a set of unique patches for each board, the upstream package developers are phasing out supporting uboot wherever possible. Instead, they recommend using Grub2 as a secondary bootloader and using the mender-grubenv package. Because the mender-grubenv file provides it's own fw_printenv script, it is not possible to know if U-Boot's fw_printenv or mender-grubenv's fw_printenv should be used. As such, remove selecting uboot tools when uboot is selected, and instead add a more comprehensive note in the help section about what Mender requires for uboot and grub2-based systems, with a link to the meta-mender github project for the base uboot patches, and a link to the official documentation on manual uboot integration.

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
