[PATCH v9 4/7] sign-file: add support to sign modules in bulk

From: Shreenidhi Shedi
Date: Wed Aug 09 2023 - 13:22:30 EST


In the existing system, we need to invoke sign-file binary for every
module we want to sign. This patch adds support to give modules list
in bulk and it will sign them all one by one.
