To be compatible with old u-boot used by lots of MT7621 devices, the u-boot needs to boot-up MT7621's all cores, and all VPES of each core. This patch adds asm/mipsmtregs.h from linux kernel which is need for boot-up VPEs. Reviewed-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
