[U-Boot] [U-boot] mmc write|read howto

Hi All,

I need some help regarding mmc write and mmc read commands usage.

I am using a 4GB SD/MMC plus and socked eMMC cards, usually I am formatting these cards on my host pc with fat partition and copy the images into card. while in the u-boot level I am reading the images from card and copy it onto mem addr like fatload mmc 0 0x1000 uImage.

Can we write the images onto these cards in u-boot level?, using mmc write. same way can we read back using mmc read? if so how to do that.

Request for help.

Thanks, Jagan.
