Proper U-Boot for Lichee Pi 4A now runs in S mode instead of M mode, which means the extra firmware, OpenSBI, must be built and integrated in the image, and the vendor U-Boot cannot chainload the result image anymore as it runs in M mode. Remove redundant information about chainloading and update build steps to mention OpenSBI firmware. Signed-off-by: Yao Zi <ziyao@disroot.org> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>
