https://toolchains.bootlin.com/ has been providing for a few years a number of ready-to-use pre-built toolchains, for a wide range of architectures (which it turns out, are all built using Buildroot). While toolchains.bootlin.com provides Buildroot config fragments to easily use those toolchains with Buildroot (see [0] for example), this is not visible anywhere. So instead, we would like to add support for these toolchains in Buildroot just like we have existing support for Linaro, ARM, Synopsys, etc. toolchains. [0] https://toolchains.bootlin.com/downloads/releases/toolchains/aarch64/fragments/aarch64--glibc--bleeding-edge-2020.02-2.frag However, the number of toolchains provided by toolchains.bootlin.com is really large, and they are regularly updated. Maintaining that manually would be time consuming and error-prone. So instead, this commit introduces a script that automatically generates: - toolchain/toolchain-external/toolchain-external-bootlin/Config.in.options - toolchain/toolchain-external/toolchain-external-bootlin/toolchain-external-bootlin.mk - toolchain/toolchain-external/toolchain-external-bootlin/toolchain-external-bootlin.hash - support/testing/tests/toolchain/test_external_bootlin.py We create a single external toolchain package, with a Kconfig "choice" as a sub-option to select the toolchain variant to be used. The script contains a Python dict that provides the mapping between the toolchains provided by toolchains.bootlin.com, and the architecture options/variants they are applicable to. The test cases allow to verify that the toolchain configuration is correct, and that it is able to build a Busybox based system. It doesn't do any runtime testing as such testing is already done by toolchains.bootlin.com: the test cases here are only meant to verify that the toolchain-external-bootlin package works as expected.

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
