Subject: [PATCH] powerpc: bootwrapper: force gzip as mkimage's compression
method
Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
instruct the mkimage to use the xz compression, which isn't
supported. This patch forces the gzip compression, which is
supported and doesn't matter because the generated uImage for
the apm821xx target gets ignored as the OpenWrt toolchain will
do separate U-Boot kernel images for each device individually.
