From 2d9b332d99b24f27f77e9ba38ce3c8beb11a81c0 Mon Sep 17 00:00:00 2001 From: Oliver O'Halloran Date: Fri, 1 Nov 2019 19:55:21 +1100 Subject: [PATCH] powerpc/xmon: Allow passing an argument to ppc_md.restart() On PowerNV a few different kinds of reboot are supported. We'd like to be able to exercise these from xmon so allow 'zr' to take an argument, and pass that to the ppc_md.restart() function.
