In linux, newer architectures like ARM64 and RISC-V keep their device tree sources organized by subdirectories. When these device trees are installed by the kernel they will keep the directory names. But buildroot strips the prefixes when installing them into /boot or the images directory. Sometimes the bootloader references the device tree by name (e.g. u-boot has the environment variable 'fdtfile') which also includes the prefix directory. Make it possible to keep this prefix during installation, so we can be compatible with other distributions and make it easier for the user, because he doesn't have to change that environment variable.

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.
