U-Boot is running fine on a Yucca Rev. B here:

U-Boot 1.1.5 (Nov 10 2006 - 08:45:01)

CPU:   AMCC PowerPC 440SPe Rev. B at 533.328 MHz (PLB=133, OPB=66, EBC=66 MHz)
       I2C boot EEPROM enabled
       Bootstrap Option C - Boot ROM Location I2C (Addr 0x54)
       Internal PCI arbiter enabled
       32 kB I-Cache 32 kB D-Cache
Board: Yucca - AMCC 440SPe Evaluation Board
I2C:   ready

Type "run flash_nfs" to mount root filesystem over NFS

Please make sure to use a current version of the U-Boot code. Support
for  440SPe  rev.  B.  needs  at  least   the   version   tagged   as
LABEL_2006_06_30_2020, or better top of tree in the git repo.
