Indeed as it is, your PATCH 1/3 alone doesn't build: it depends on files added by PATCH 3/3. > configs/chromebook_elm_defconfig | 35 ++++++++++++++++++++++++++++++++ > 1 file changed, 35 insertions(+) > create mode 100644 configs/chromebook_elm_defconfig > > diff --git a/configs/chromebook_elm_defconfig b/configs/chromebook_elm_defconfig > new file mode 100644 > index 0000000000..9b467ec6a8 > --- /dev/null > +++ b/configs/chromebook_elm_defconfig > @@ -0,0 +1,35 @@ > +# Architecture > +BR2_aarch64=y > +BR2_cortex_a72_a53=y > + > +# Filesystem > +BR2_TARGET_ROOTFS_EXT2=y > +BR2_TARGET_ROOTFS_EXT2_4=y You'll need a: BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_5_9=y but this option doesn't exist yet, so we'll have to add it. Other than that, the defconfig looks good to me. Best regards, Thomas

The architecture of the MT8173 SoC is armv8-a in a big-little config. This SoC is supported by the Chrome-OS linux kernel, but the mainline support is reasonably good as well (benchmarks / conformance run fine) and so that is used. For now, the kernel is 5.9-rc5 which will be uprevd to 5.9 once its released. The defconfig also lists all the tools (parted, vboot) that are necessary to create a bootable image.
