From 4934fbfb3ff09b8500f63d4624ed8b41647bb822 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 21 Oct 2022 10:03:52 +0200 Subject: parisc: Show MPE/iX model string at bootup Some (mostly 64-bit machines) machines allow to run MPE/iX and report the MPE model string via firmware call. Enhance the pdc_model_sysmodel() function to report that model string. Note that some 32-bit machines like the B160L wrongly report success for the firmware call, so include a check to prevent showing wrong info.
