From 34743e9633ab4a76a9bbcf55a0daa11cb2be58c4 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 14 Aug 2020 21:09:40 +0200 Subject: hw/hppa: Change fw_cfg port address Devices on hppa occupy at least 4k starting at the HPA, so MEMORY_HPA+4k is blocked (by Linux) for the memory module. I noticed this when testing the new Linux kernel patch to let the fw_cfg entries show up in Linux under /proc. The Linux kernel driver could not allocate the region for fw_cfg. This new base address seems to not conflict.
