configs/chromebook_elm: new defconfig
This commit adds supports for building buildroot kernel + rootfs for MT8173 Elm board, also known as Chromebook Elm (https://www.acer.com/ac/en/US/content/series/acerchromebookr13). Though Chrome-OS is officially supproted on this board, the mainline kernel works as well (benchmarks + conformance), and so the 5.9 kernel is used. As the 5.9 kernel isn't yet released, we use the 5.9-rc5 for now, which will be up-revd to 5.9 once its released. Using the mainline kernel means that we have to apply certain patches to get the HDMI screen working. These patches are lying in the "drm-misc-next" list and will make it to the kernel after 5.9. At that time, we will remove the patches and point Buildroot to use the latest kernel (hopefully, 5.10). This commit also adds an ITS file (for creating FIT images), an ARGS file (for providing kernel args) and a "sign.sh" script to generate signed kernel images. Though the "sign.sh" is very similar to the coresponding file under board/chromebook/snow, it cannot be shared between both boards, as the script requires access to the board specific its / args file. Additionally a readme & defconfig is added to help the user get started. Signed-off-by: Bilal Wasim <bilalwasim676@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
