From ebad6a4230bdb5927495e28bc7837f515bf667a7 Mon Sep 17 00:00:00 2001 From: Andrey Panin Date: Tue, 6 Sep 2005 15:18:29 -0700 Subject: [PATCH] dmi: add onboard devices discovery This patch adds onboard devices and IPMI BMC discovery into DMI scan code. Drivers can use dmi_find_device() function to search for devices by type and name.
