Barebox provides an option to embed a custom environment image into barebox binary. This image will be used, when the environment found in the environment sector is invalid. Both embedded and external images can be used together, so having both options at the same time is justified. This patch sets barebox Kconfig option CONFIG_DEFAULT_ENVIRONMENT_PATH to user specified path. This way one can use such BR's variables like BR2_EXTERNAL, TOPDIR etc. to provide paths to custom environment folders.

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.
