From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Thu, 2 May 2019 10:52:15 -0600 Subject: [U-Boot] [PATCH v3 05/18] x86: sysreset: Implement the get_last() method In-Reply-To: <20190502165229.203099-1-sjg@chromium.org> References: <20190502165229.203099-1-sjg@chromium.org> Message-ID: <20190502165229.203099-6-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add a default implementation of this method which always indicates that the last reset was a power-on reset. This is the most likely type of reset and without a PCH-specific driver we cannot determine any other type.
