Weijie Gao has submitted an updated version of the patchset adding support for MT7986 and MT7981 to U-Boot. Use that v2 patchset. Changes of v2: - Add cpu driver for print_cpuinfo() - Fix NULL pointer dereference in mtk_image (was already fixed in OpenWrt) - Fix coding style - Minor changes https://patchwork.ozlabs.org/project/uboot/list/?series=316148 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
