From ff954c5b73c4010f9984e0c543779f3692767c0c Mon Sep 17 00:00:00 2001
From: Leah Rowe <leah@libreboot.org>
Date: Sat, 27 May 2023 11:44:54 +0100
Subject: unify download/build scripts
move resources/scripts/download/ to:
resources/scripts/update/module/
This: ./download coreboot
Is now: ./update module coreboot
However, running "./download coreboot"
still works, via backwards compatibility.
