From 8fefb2fd60203ee8f3bbd1f84bdfd36da7f78214 Mon Sep 17 00:00:00 2001 From: Anton Johansson Date: Thu, 5 Mar 2026 23:54:22 +0100 Subject: [PATCH] hppa: Use 44 bit physical addresses for PA-8700 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is in line with the PA-8700 specification which demands 44 bits. However, this change breaks the SeaBIOS functional tests as the firmware assumes 40 bit physical addresses. Therefore, change the functional tests to instead run on an A400 which has the expected physical address space size.
