how to select a root file system (there are multiple of them in flash) from u-boot


In the flash of the board I am working on, there are multiple root file systems in the flash. By default U-boot loads root0. So how do I select any of them as I wish?
Here is the partitions in the flash:

device nand0 <maximasp_nand.0>, # parts = 9
#: name size offset mask_flags
0: u-boot 0x00200000 0x00000000 1
1: env0 0x00080000 0x00200000 1
2: env1 0x00080000 0x00280000 1
3: kernel0 0x00400000 0x00300000 0
4: kernel1 0x00400000 0x00700000 0
5: kernel2 0x00500000 0x00b00000 0
6: root0 0x06400000 0x01000000 0
7: root1 0x06400000 0x07400000 0
8: other 0x12800000 0x0d800000 0

active partition: nand0,8 - (other) 0x12800000 @ 0x0d800000

Don't you use bootargs as in any Linux system? I don't use U-Boot, but from I guess that would be a way.
