From 091c466e26867656d3d650a3a5a40169b97648a1 Mon Sep 17 00:00:00 2001 From: Shameer Kolothum Date: Wed, 18 Sep 2019 14:06:23 +0100 Subject: hw/acpi: Make ACPI IO address space configurable This is in preparation for adding support for ARM64 platforms where it doesn't use port mapped IO for ACPI IO space. We are making changes so that MMIO region can be accommodated and board can pass the base address into the aml build function. Also move few MEMORY_* definitions to header so that other memory hotplug event signalling mechanisms (eg. Generic Event Device on HW-reduced acpi platforms) can use the same from their respective event handler code.
