[U-Boot] How to enable FAT fs support and hook up the SD/MMC driver

Hello,

I am a newbie in this area. I want to enable FAT file system support for U-Boot. But I am unsure as to what CONFIG options I should tweak for this. Also, I want to know where are the file system MMC/SD hooks, so that I can hook up my MMC/SD driver to be used by the FAT filesystem.

I would appreciate any pointers.

Thanks, Djoker
