This patch set implements support for the ACPI hardware-reduced specification.
The changes are coming from the NEMU [1] project where we're defining a new x86 machine type: i386/virt. This is an EFI only, ACPI hardware-reduced platform and as such we had to implement support for the latter. As a preliminary for adding hardware-reduced support to QEMU, we did some ACPI code reorganization with the following goals: * Share as much as possible of the current ACPI build APIs between legacy and hardware-reduced ACPI. * Share the ACPI build code across machine types and architectures and remove the typical PC machine type dependency. Eventually we hope to see arm/virt also re-use much of that code. The rest of the patchset adds the hardware-reduced support on top of this code reorganization. Here again, the implementation is machine type, platform and architecture independent.
