the `--layout` parameter needs a special file that only specifies the
layout. You'd still give your flash image to the `-w` parameter. Please
read the section about the `--layout` parameter in the flashrom manual
page (e.g. [1]).

As you are working with coreboot, you can generate the layout file from
the flash image with ifdtool's `-f` parameter (it's in util/ifdtool/ in
the coreboot source tree).

Hope that helps,
Nico
