   4 Subject: [PATCH] powerpc: bootwrapper: force gzip as mkimage's compression
   5  method
   6
   7 Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
   8 instruct the mkimage to use the xz compression, which isn't
   9 supported. This patch forces the gzip compression, which is
  10 supported and doesn't matter because the generated uImage for
  11 the apm821xx target gets ignored as the OpenWrt toolchain will
  12 do separate U-Boot kernel images for each device individually.
