ar71xx: Ubiquiti Airmax M: add relocate-kernel to invalidate cache
Some Ubiquiti U-boot versions, in particular the "U-Boot 1.1.4.2-s956 (Jun 10 2015 - 10:54:50)" found with AirOS 5.6, do not correctly flush the caches for the whole kernel address range after decompressing the kernel image, leading to hard to debug boot failures, depending on kernel version and configuration. As a workaround, prepend the relocate-kernels loader, which will invalidate the caches after moving the kernel to the correct load address. Reported-by: Andreas Ziegler <dev@andreas-ziegler.de> Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
