[SAMI] I believe this brings the dependency on QemuBootOrderLib which requires QemuFwCfgLib. Is there a way to to implement QemuBootOrderLibNull to remove the dependency on QemuFwCfgLib? The QemuBootOrderLib APIs ConnectDevicesFromQem(),StoreQemuBootOrder(),SetBootOrderFromQemu () and GetFrontPageTimeoutFromQemu ()  could return something like EFI_UNSUPPORTED in QemuBootOrderLibNull.

Can you check, please?
