Hi We are using AT91sam9261, till date we had never interfaced SDCARD in units . Now we need SDCARD interface in our units. for that i tried to compile u-boot i encountered problems, which are attached as MMC.log please get the attachement. and also we need mmc.h which is missing in u-boot path asm/arch/mmc.h
This is the basic problem when I compile my u-boot version(u-boot-2008.10) for SDMMC CARD

when i comment //#include <asm/arch/mmc.h> this section of code in "include/mmc.h" file, and try to compile i encountered the following problem.

U-Boot v2008.10 is about 3 years old, i. e. hopelessly obsolete and no longer supported here. Please update and use recent code instead (say, v2011.09).

This is obviously a result of your modifications to the code. Please fix such errrors and warnings as they are raised, one by one, step by step.

This is obsolete code, please update.
On the other hand, I'm not sure if there is any MMC support for AT91 at all in mainline...
Best regards,
Wolfgang Denk
