How can I configure the MMC port on the OMAP3503 to work in 4 bit mode and high speed in linux?

Thanks

    This is currently handled in the PSP release itself. The omap_hsmmc driver implementation can handle 1/4/8 bit modes and it is left to the platform driver(specific to the board) to setup the mux configuration and pass the mode information to the omap_hsmmc driver.

    Can you look at the way this is done for omap3evm/beagle boards. Look under arch/arm/mach-omap2 folder for board specific files
