* mci: Fix 8 bit mmc cardsSascha Hauer2012-02-091-0/+1
| | | | | | | | | | Currently we test the cards capabilities for being 8bit capable. This does not work since noone ever sets this bit. Unfortunately there is no bit to test 8bit capability, so we introduce a patch from the kernel which puts the mmc card into 8bit mode and tests whether it can succesfully read the ext_csd in this mode.

* mci: Use struct mci for internal argument passingSascha Hauer2012-02-091-5/+2
| | | | | | | | | The mci layer currently passes around a struct device_d for its internal use. Apart from being confusing this drops typesafety for no good reason. Instead, pass around a struct mci. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: remove unused device argument from set_iosSascha Hauer2012-02-091-1/+1
| | | | | | This argmuent is unused in all drivers, so remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci core: replace discrete ios values with struct iosSascha Hauer2012-02-091-1/+31
| | | | | | | As we'll need more arguments to set_ios over time put them in a struct mci_ios like the kernel does. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mci: Add complete definitions for the card typeSascha Hauer2012-02-091-2/+10
| | | | | | | Add the different DDR types and also a definition for the card type mask. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Use generic block layer to access the drives and do partition parsingJuergen Beisert2011-11-281-1/+2

* mci: Add MCI over SPI supportFranck Jullien2011-11-251-0/+18
| | | | | | | | | | | This patch adds MMC over SPI support to mci-core.c and mci_spi.c driver. This driver is useful when SOC doesn't have built-in MCI component. Tested with nios, 2Go SD-CARD and FAT file system. Signed-off-by: Franck Jullien <franck.jullien@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add MCI card support to bareboxJuergen Beisert2010-10-111-0/+239
This adds the basic framework to handle MCI cards in barebox. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
