"virt" is a funny case because there is no underlying hardware that we're trying to match. So it is whatever we say it is and we've said it's two separate pflash chips. We don't need to change that I think. (IIRC this is derived partly from OVMF usecase requirements and partly from the vexpress devboards having 2 flash chips.) thanks -- PMM
