in vivi if can use bon to set partitionsand in DULG Manual i see something like "root=/dev/mtdblock2" in BOOTARGS.but i can't find the defination of mtd partition in /board/smdk2410/smdk2410.c or smdk2410.h.and i wonder whether i must set "root=/dev/mtdblockX" in my BOOTARGS or i can just set the physical address of root-cramfs in NAND flash?

i use uboot loadb command to place kenerl on 0x32000000, root.cramfs on 0x30800000,and when i type bootm 32000000 30800000, it just boot as there is a ramdisk image.Does uboot support boot cramfs rootfs in ram? what's the command?
U-Boot can be used to load a cramfs image (or any other file) into RAM. All the rest is not an U-Boot issue, but a question if your Linux kernel knows how to deal with such a setup.
