Subject: [PATCH 6/9] sim: msp430: add basic SMP cpu init
Date: Sun, 25 Dec 2022 02:14:31 -0500	[thread overview]
Message-ID: <20221225071434.30014-6-vapier@gentoo.org> (raw)
In-Reply-To: <20221225071434.30014-1-vapier@gentoo.org>

There's no need to assert there's only 1 CPU when setting them all
up here is trivial.
