581	help
582	  This selects support for Elan Digital Systems' VUB300 chip.
583
584	  The VUB300 is a USB-SDIO Host Controller Interface chip
585	  that enables the host computer to use SDIO/SD/MMC cards
586	  via a USB 2.0 or USB 1.1 host.
587
588	  The VUB300 chip will be found in both physically separate
589	  USB to SDIO/SD/MMC adapters and embedded on some motherboards.
590
591	  The VUB300 chip supports SD and MMC memory cards in addition
592	  to single and multifunction SDIO cards.
593
594	  Some SDIO cards will need a firmware file to be loaded and
595	  sent to VUB300 chip in order to achieve better data throughput.
596	  Download these "Offload Pseudocode" from Elan Digital Systems'
597	  web-site http://www.elandigitalsystems.com/support/downloads.php
598	  and put them in /lib/firmware. Note that without these additional
599	  firmware files the VUB300 chip will still function, but not at
600	  the best obtainable data rate.
601
602	  To compile this mmc host controller driver as a module,
603	  choose M here: the module will be called vub300.
604
605	  If you have a computer with an embedded VUB300 chip
606	  or if you intend connecting a USB adapter based on a
607	  VUB300 chip say Y or M here.
