[RFC PATCH 3/4] jumparch64: insert into bootm

[Frank Wunderlich <linux@fw-web.de>]

From: Frank Wunderlich <frank-w@public-files.de>

if uboot is 32bit and linux-kernel is 64bit packed into armhf mkimage
(like official kernels for bpi-r64) call jumparch64 to switch to 64bit
mode after unpacking the kernel-image
