Hi Tahnia,

> I am unfortunately not able to help you, since I myself am still new to coreboot (and to BIOS development in general).
No worries, we'll get there eventually :)

> When you ran the Intel-provided version (stitched with the Windows tool), did you experience any similar problems with the USB controller in U-Boot? If so, did you manage to solve it?
We are looking at this at the moment. Early investigation suggests that U-Boot needs a device tree for Leaf Hill. Without that, U-Boot isn't aware of ant USB controllers, SPI Flash, PCI devices or anything.
That's all I know at the moment, you might be better asking in the U-Boot mailing list.

Unfortunately it looks like Intel don't bother providing a device tree for Leafhill. So we may end up writing our own, which I hear is a bit pernickety.
