PS1, Line 296: layout->entries[i].included = false;
> Should this line also move into flashrom_layout_release() ?

Even better, zero the whole entry.

PS1, Line 279: layout_cleanup_args
> This function is not cleaning up the layout anymore, only args. […]

It's still layout args specifically so I'd like to keep 'layout', but layout_args_cleanup seems a little better.
