Subject: [PATCH] [PATCH] copy-firmware.sh: Support passing in firmware files to install

From: Mike Pagano <[email-masked]>
Date: Sat, 23 Dec 2023 13:14:58 -0500

This change adds support to copy-firmware.sh to accept a space separated
list of firmware files to install.

This allows our users to define a small subset of needed firmware files
their system requires without installing every firmware file included
from the repository.
