+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.
