Yes, there is.

For example:

=> mtdparts -?
mtdparts - define flash/nand partitions

Usage:
mtdparts 
    - list partition table
mtdparts delall
    - delete all partitions
mtdparts del part-id
    - delete partition (e.g. part-id = nand0,1)
mtdparts add <mtd-dev> <size>[@<offset>] [<name>] [ro]
    - add partition
mtdparts default
    - reset partition table to defaults

-----

this command uses three environment variables:

'partition' - keeps current partition identifier

partition  := <part-id>
<part-id>  := <dev-id>,part_num

'mtdids' - linux kernel mtd device id <-> u-boot device id mapping

mtdids=<idmap>[,<idmap>,...]

<idmap>    := <dev-id>=<mtd-id>
<dev-id>   := 'nand'|'nor'|'onenand'<dev-num>
<dev-num>  := mtd device number, 0...
<mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)

'mtdparts' - partition list

mtdparts=mtdparts=<mtd-def>[;<mtd-def>...]

<mtd-def>  := <mtd-id>:<part-def>[,<part-def>...]
<mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)
<part-def> := <size>[@<offset>][<name>][<ro-flag>]
<size>     := standard linux memsize OR '-' to denote all remaining space
<offset>   := partition start offset within the device
<name>     := '(' NAME ')'
<ro-flag>  := when set to 'ro' makes partition read-only (not used, passed to kernel)



=> mtdparts   

device nor0 <fc000000.flash>, # parts = 7
 #: name                size            offset          mask_flags
 0: firmware            0x00100000      0x00000000      0
 1: dtb                 0x00040000      0x00100000      0
 2: kernel              0x00240000      0x00140000      0
 3: small-fs            0x00280000      0x00380000      0
 4: initrd              0x00200000      0x00600000      0
 5: misc                0x00800000      0x00800000      0
 6: big-fs              0x01000000      0x01000000      0

active partition: nor0,0 - (firmware) 0x00100000 @ 0x00000000

defaults:
mtdids  : nor0=fc000000.flash
mtdparts: mtdparts=fc000000.flash:1m(firmware),256k(dtb),2304k(kernel),2560k(small-fs),2m(initrd),8m(misc),16m(big-fs)
