You cannot. The *root* filesystem is always just a single file system.

You can mount  additional  file  systems  on  top  of  the  directory
hierarchy  provided  by  your root file system, but this is something
completely different.

There are several errors in this text.

First, the kernel download address 0x40000 = 256kB is  much  too  low
and can never work.

Second, the "100000" parameter is not a "RootFS1 address". It  is  the
start  address  of  a ramdisk image. This may or may not be your root
file system, and it is usually NOT the address as seen by the kernel.
And, 100000 = 1 MB is a much too low address and can never work.


And finally: all this has absolutely NOTHING to do with MTD partitions.

Best regards,
