Subject: [Qemu-devel] [PATCH v2 2/5] smbios: Move table build tools into an include file.
Date: Wed, 11 May 2016 11:38:51 -0500 [thread overview]
Message-ID: <1462984734-23803-3-git-send-email-minyard@acm.org> (raw)
In-Reply-To: <1462984734-23803-1-git-send-email-minyard@acm.org>
From: Corey Minyard <cminyard@mvista.com>
This will let things in other files (like IPMI) build SMBIOS tables.
Signed-off-by: Corey Minyard <cminyard@mvista.com>
