commit: https://git.buildroot.net/buildroot/commit/?id=293196b2baecd27bc41107393a72cf4aeb5f11bc
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This patch adds the defconfig file needed to build u-boot, kernel
and rootfs for the Rock 5B. In addition it adds a kernel config
fragment file, which activates the needed ethernet driver support.
It also adds a readme and post image scripts, needed to generate an
sdcard.img file, which can be flashed on an SD card to boot the
Radxa Rock 5B.
