Yes, this has been done with mPCIe. There is driver "Oxford OXPCIe952" and the source has some hints of the marketing names you can find a tested adapter with. You also need EARLY_PCI_BRIDGE=y in your coreboot build to tell which PCIe root port this card is plugged into. For ExpressCard some additional power management may come into play, not demonstrated afaics. Kyösti -- coreboot mailing list: [email protected] https://mail.coreboot.org/mailman/listinfo/coreboot
