This driver is broken since 2.6.31 when the traditional i.MX1 support was removed. In theory the i.MX1 mmc controller can be supported by the mxcmmc driver which basically is the same hardware. However, the i.MX1 controller has severe bugs which made several workarounds necessary which resulted in a different driver structure. At that time it seemed easier to write a second driver to support hardware without bugs. As noone cared for the i.MX1 driver for a long time and it does not compile, remove it.

|

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

Note: These controllers only support SDIO cards and do not
|
|
support MMC or SD memory cards.
