From e274d2a777de168082b36a31b6b5ea2b9185e960 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Sat, 11 Nov 2023 20:13:53 +0100 Subject: [PATCH] hw/hppa: Move software power button address to page zero Something appears to be off between the 64-bit CPU, the 32-bit PDC (SeaBIOS-hppa firmware), and the 64-bit kernel in addressing the power button address in high-mapped firmware memory. Use a 32-bit value at PAGE0->pad0[4] instead.
