This driver provides support for Alcor Micro AU6601 and AU6621
card readers.

This is single LUN HW and it is expected to work with following standards:
- Support SDR104 / SDR50
- MultiMedia Card (MMC)
- Memory Stick (MS)
- Memory Stick PRO (MS_Pro)

Since it is a PCIe controller, it should work on any architecture
supporting PCIe. For now, it was developed and tested only on x86_64.

This driver is a result of RE work and was created without any
documentation or real knowledge of HW internals.
