[U-Boot] Booting from ext2/ext3

Indeed, there was something missing! I added the configurations like
described in doc/README.usb:

CONFIG_CMD_USB
CONFIG_USB_UHCI
CONFIG_USB_STORAGE

It seems, like these aren't sufficient - again at final linking stage I get
missing references (see attachment).

At least disk/part.o has some symbols now:

00000000 d block_drvr
000000dc T dev_print
0000031c T get_dev
000002a0 T get_partition_info
         U get_partition_info_dos
000002dc T init_part
00000004 T print_part
         U print_part_dos
         U printf
         U puts
         U strlen
         U strncmp
         U test_part_dos
         U usb_stor_get_dev

Anyhow, get_partition_info_dos and others are undefined :-(

The goal is to boot from an USB Disk-on-Module, formatted either ext2/3 or
maybe FAT.

Happy Easter - all!
Matthias
