"""Recipe for building OVMF firmware and uploading them to CIPD.

The Open Virtual Machine Firmware (OVMF) project supports firmware for Virtual
Machines (e.g., QEMU). The produced OVMF_CODE.fd and OVMF_VARS.fd are used to
emulate EFI bootloading in QEMU in order to boot Zircon off of disk. Currently
this is only supported for x64.
