From e3cb3a4072ffc2d3db9c9363d5b2ebd58adbdfb7 Mon Sep 17 00:00:00 2001
From: Leah Rowe <leah@libreboot.org>
Date: Thu, 9 May 2024 13:52:49 +0100
Subject: merge script/build/serprog with script/build/roms

previous command:

./build serprog

now it is:

./build roms serprog

after that, it's the same arguments e.g.

./build roms serprog stm32
./build roms serprog rp2040

further cleanup to commence
