From 150ee013ed3f2af7eec493cd68ae774a85d40a2b Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 24 Jun 2022 14:40:36 +0100 Subject: pckbd: introduce new I8042_MMIO QOM type Currently i8042_mm_init() creates a new KBDState directly which is used by the MIPS magnum machine. Introduce a new I8042_MMIO QOM type that will soon be used to allow the MIPS magnum machine to be wired up using standard qdev GPIOs.
