BSS footprint of fat.c is very high. It has three buffers each of size 64KB. To workaround this problem I have done something like below(The way x-loader works around this problem today). CONFIG_SYS_SPL_FAT_BUFFER_BASE is in SDRAM.Is this ok?

Also, I was wondering why we need 3 such scratch buffers in this implementation. I do not understand this code. But I was wondering if we could work with just one 64K buffer?

i'd be pretty surprised if these couldnt be cleaned up in some way. sucking up 64KiB * 3 just for vfat is pretty f-in crazy. no other FS code needs this. -mike
