Thanks for your reply.
This is for my embed system upgrade, I reserved one nand partition for filesystem
environment which will load to DDR while uboot booting.
This filesystem.uboot file should be able to read both by uboot and kernel, and
maybe written by uboot and kernel. There will be no filesystems upon the nand in
case the loader may not support some filesystem types while uboot booting.

Seems that the trimmed environment of OS has get rid of the mtd-tools, So the dd
command was the most convenience tools to use by hand.

Thanks.
