Message-ID: <1308272892.2516.105.camel@pasglop>
Date: Fri, 17 Jun 2011 11:08:12 +1000
From: Benjamin Herrenschmidt <benh@...nel.crashing.org>
To: linuxppc-dev <linuxppc-dev@...ts.ozlabs.org>
Cc: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>
Subject: [PATCH 1/5] powerpc/hvsi: Move HVSI protocol definitions to a
header file
This moves various HVSI protocol definitions from the hvsi.c
driver to a header file that can be used later on by a udbg
implementation
Signed-off-by: Benjamin Herrenschmidt <benh@...nel.crashing.org>
