Strange...

Indeed. That's nothing.

It seems you are missing the device driver support. If you check the
code in "disk/part.c" you will see this:

...
218 #if (defined(CONFIG_CMD_IDE) || \
219      defined(CONFIG_CMD_MG_DISK) || \
220      defined(CONFIG_CMD_SATA) || \
221      defined(CONFIG_CMD_SCSI) || \
222      defined(CONFIG_CMD_USB) || \
223      defined(CONFIG_MMC)                || \
224      defined(CONFIG_SYSTEMACE) )
225
226 #if defined(CONFIG_MAC_PARTITION) || \
227     defined(CONFIG_DOS_PARTITION) || \
228     defined(CONFIG_ISO_PARTITION) || \
229     defined(CONFIG_AMIGA_PARTITION) || \
230     defined(CONFIG_EFI_PARTITION)
...

You have CONFIG_DOS_PARTITION defined, which satisfies the second
block conditions; please check if you also have IDE, MG_DISK, SATA,
SCSI, USB, MMC or SYSTEMACE enabled in your configuration - and if
not, then please explain which device you actually intend to use?

Best regards,

Wolfgang Denk
