From 245f5cda69a1332585c2a22a48420f4ca1ab67ad Mon Sep 17 00:00:00 2001 From: Mario Six Date: Mon, 6 Aug 2018 10:23:32 +0200 Subject: sysreset: Add get_status method It's useful to have the reset status of the SoC printed out during reset (e.g. to learn whether the reset was caused by software or a watchdog). As a first step to implement this, add a get_status method to the sysreset class, which enables the caller to get printable information about the reset status (akin to get_desc in the CPU uclass).
