From d8c33e134205a85ffcc303fac61c3e5584a3db5e Mon Sep 17 00:00:00 2001 From: Geoffroy Van Cutsem Date: Fri, 5 Mar 2021 14:12:58 +0100 Subject: [PATCH] doc: add missing 'mmio@' description to hypervisor parameters Add the 'mmio@' parameter to the document describing all the possible values for 'uart='. This is the command-line argument passed to the hypervisor in order to overwrite and/or set the serial port.
