From c12b1e67d50c01f6ba78abcdaaa533abaf71b664 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Wed, 26 Oct 2022 21:06:36 +0200 Subject: [PATCH] hw/isa/piix4: Correct IRQRC[A:D] reset values MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit IRQRC[A:D] registers reset value is 0x80. We were forcing the MIPS Malta machine routing to be able to boot a Linux kernel without any bootloader. We now have these registers initialized in the Malta machine write_bootloader(), so we can use the correct reset values.
