This is my first post to the list.
I am using u-boot-1.3.4 in buildroot-2011.11 My device is a at91sam9g20-ek
I have a patch adding: include/configs/at91sam9g20ek.h which I gather acts as a config file for u-boot.

U-Boot> help
does not list mtdparts

But my bootargs does use it:
bootargs=mem=64M console=ttyS0,115200 mtdparts=atmel_nand:4M(bootstrap/uboot/kernel)ro,60M(rootfs),-(data) root=/dev/mtdblock1 rw rootfstype=jffs2

Is there a trick to add the mtdparts command? Or is there supposed to be a command?

I unsuccessfully added to include/configs/at91sam9g20ek.h #define CONFIG_JFFS2_NAND 1
#define CONFIG_JFFS2_CMDLINE 1
#define CONFIG_CMD_JFFS2 1 // Required to include cmd_jffs2.c which did not result in adding the command line.

This mtdparts is defined for Linux kernel NAND driver.

Yes, you need to add "#define CONFIG_CMD_MTDPARTS" in

include/configs/at91sam9g20ek.h

I had the impression there was also an interactive command-line tool for mtdparts, from the u-boot prompt.

Yes, you need to add "#define CONFIG_CMD_MTDPARTS" in

I added this to include/configs/at91sam9g20ek.h

Now it contains:
#define CONFIG_JFFS2_NAND 1
#define CONFIG_JFFS2_CMDLINE 1
#define CONFIG_CMD_JFFS2
#define CONFIG_CMD_MTDPARTS"

This post give me the impression that there should be a uboot mtdparts command in addtion to the kernel option.

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

Adding CONFIG_CMD_MTDPARTS won't work, this option is not available in this very old U-Boot v1.3.4. CONFIG_JFFS2_CMDLINE should add mtdparts command. Please double check where you add this option and ensure that it is not added in some #ifdef ... #elif ... #endif construct. Depending on the CFG_USE_* build options some options in the config file may have no effect at all.
