    We have a board with an 8-bit connected eMMC and Linux only used 4-bit wide
    bus access. After some research IMO the device is only matched to the default
    PCI id class
    > PCI_DEVICE_CLASS((PCI_CLASS_SYSTEM_SDHCI << 8), 0xFFFF00)

    AFAICS it's the same issue with the Medfield eMMC where 8-bit bus support is
    added in 0d013bcf5c272faea1f8e7a5ef3cb2e98103d5cb
    This also states the default is 4-bit bus width which I saw before.

    Regards,
    Alexander
