From f77ab00e898bb24323d027f3f27c5661e19c8461 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 2 May 2019 10:52:15 -0600 Subject: [PATCH] x86: sysreset: Implement the get_last() method 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.
