For signed EC RW images (CONFIG_RWSIG), there's no point in embedding the public key or signature into the image itself since it will just be replaced by the signer (either as the next step in the build process, or after the fact for MP releases). This takes that out and just points to where the pubkey and signature will be placed. BUG=none BRANCH=none TEST=make buildall I also checked the signatures with futility show -t build/*/ec.bin They still look good, and the one signed image I booted (Cr50) works as before.
