[coreboot] USB Support on Apollo Lake

Hi Experts,

Does coreboot support USB port initialization in legacy mode on Apollo Lake
as some of the BIOS does so that grub or other payloads can use it as
USB2.0?

There is no USB2.0 port on this board and Grub2 doesn't support xhci so we
seems to be reaching to a dead end.

I am trying to see if the dual role USB ports can be initialized in
coreboot/fsp so that they can act as USB2.0 for payloads.

Thanks
