What do you mean with "root fs" ? If this is  a  ramdisk  image,  you
don;t need any flash support in the Linux kernel at all.

This refers to our (old) character device flash driver. It  does  not

need a block device than - i. e. support for MTD.

Why don't you have a Linux partition installed so you can be  working
in  a  programmer-friendly environment instead of a keep-gates'-bank-
account-happy one? :-)                            -- Tom Christiansen
