Hi,
Intel Quark consists of one SDIO host controller which can be PCI enumerated.
SDHCI-PCI layer doesn't support it. Thus, we add support for Intel Quark SDIO as well.

On Intel Quark, there is a SDIO host controller. This patch is added to
enable the SDIO host controller.

Please read the comment at the top of pci_ids.h:
* Do not add new entries to this file unless the definitions
* are shared between multiple drivers.
If the ID you're adding is shared, please mention the sharing in your changelog.
