[PATCH u-boot-mvebu v3 22/41] tools: dumpimage: Show error message when trying to extract data from kwbimage

[Marek Behún]

From: Pali Rohár <pali at kernel.org>

There is no code for extracting data from kwbimage, so show an error
message when user tries this via e.g. dumpimage call:
  ./tools/dumpimage -T kwbimage -o /tmp/out u-boot-spl.kwb
