I would like to backport the Marvell SDIO driver to u-boot.

I have complete the 'port' of the Marvell's uboot sources code for a legacy like driver.

It will be better to make a "new" driver and I look for informations about the generic MMC driver coding style.

Can anyone tell me the needed features or point me to technical references ?

i dont think there are any docs. look at include/mmc.h and existing drivers in drivers/mmc/ that *dont* implement the legacy funcs (like mmc_legacy_init). -mike
