[PATCH 0/6] ArmVirtPkg: don't forward the DT to the OS if QEMU provides ACPI

[Laszlo Ersek <lersek@redhat.com>]

This series replaces the PURE_ACPI_BOOT_ENABLE build option with dynamic
behavior, matching QEMU's (inverse sense) "-no-acpi" switch. In
particular, DT and ACPI are no longer exposed to the guest at the same
time. (DT is exposed with "-no-acpi", or else ACPI is exposed without
"-no-acpi".)

Repo:   https://github.com/lersek/edk2.git
Branch: dynamic_pure_acpi
RHBZ:   https://bugzilla.redhat.com/show_bug.cgi?id=1430262

Tested with RHEL-7.3 for ARM and Fedora 24 guests (DT vs. ACPI).
