It actually reads this:
#define CONFIG_JFFS2_NAND 1
#define CONFIG_JFFS2_CMDLINE 1
#define CONFIG_CMD_JFFS2 1 // Required to include cmd_jffs2.c
#define CONFIG_CMD_MTDPARTS 1 // Required for mtdparts command in uboot

But the command is not available on my system.
Would it help to post my .h or maybe my build log?
