[Test Case] Boot an armhf guest in EFI mode. Here's how I do that on an arm64 box that supports AArch32: sudo qemu-system-aarch64 -enable-kvm -M virt,gic_version=host -smp 7 -m 2048 -cpu host,aarch64=off -nographic -pflash AAVMF32_CODE.fd -pflash AAVMF32_VARS.fd -drive if=none,file=bionic-server-cloudimg- armhf.img,id=hd0 -device virtio-blk-device,drive=hd0 -drive if=none,file=my-seed.img,id=hd1 -device virtio-blk- device,drive=hd1 -drive if=none,file=debian.img,id=hd3 -device virtio- blk-device,drive=hd3 -netdev type=tap,id=net0 -device virtio- net-device,netdev=net0,mac=<REDACTED> [Fix] 33412b8673135 efi/arm: Revert deferred unmap of early memmap mapping [Regression Risk] This change is specific to efi/arm, which currently doesn't boot. The reverted change was to allow for ACPI BGRT code, which isn't supported on 32-bit ARM.
