Testing ACPI changes under Windows

When testing ACPI changes in coreboot against Windows 8 or newer, beware that during a normal boot after a clean shutdown, Windows will use the fast startup mechanism which results in it not evaluating the changed ACPI code but instead using some cached version which won't include the changes that were supposed to be tested. In order for Windows to actually use the new ACPI tables, either disable the fast startup or just tell Windows to do a reboot which will make it read and use the ACPI tables in memory instead of an outdated cached version.
