From f2ffd6fb4059d22e18b23c2112419320345aeacf Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 2 Feb 2024 22:53:08 +0100 Subject: [PATCH] lasi: allow access to LAN MAC address registers Firmware and qemu reads and writes the MAC address for the LASI LAN via registers in LASI. Allow those accesses and return zero even if LASI LAN isn't enabled to avoid HPMCs (=crashes).
