From 21a78706addd15fcc682f556566c303a463fcda1 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 23 May 2013 14:17:05 -0700 Subject: [PATCH] smbios: Add generic type41 write function Mainboards were defining their own SMBIOS type41 write function. Instead pull this into the generic SMBIOS code and change the existing mainboards to make use of it.
