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

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)

If you're not part of the solution, then you're part of the precipi-
