DOC_CONTENTS="This package contains the tianocore edk2 UEFI firmware for 64-bit x86
virtual machines. The firmware is located under
	/usr/share/edk2-ovmf/OVMF.fd
	/usr/share/edk2-ovmf/OVMF_CODE.fd
	/usr/share/edk2-ovmf/OVMF_VARS.fd

The firmware does not support csm (due to no free csm implementation
available). If you need a firmware with csm support you have to download
one for yourself. Firmware blobs are commonly labeled
	OVMF{,_CODE,_VARS}-with-csm.fd

In order to use the firmware you can run qemu the following way

	$ qemu-system-x86_64 \
		-drive file=/usr/share/edk2-ovmf/OVMF.fd,if=pflash,format=raw,unit=0,readonly=on \
		...

You can register the firmware for use in libvirt by adding to /etc/libvirt/qemu.conf:
	nvram = [
		\"/usr/share/edk2-ovmf/OVMF_CODE.fd:/usr/share/edk2-ovmf/OVMF_VARS.fd\"
	]"
