I didn't want to believe  it,  but  it  seems  that  you  are  right:
Metrowerks  seems to have changed U-Boot in some incompatible way. As
them for the source code of the version they distribute,  and  please
let me know if there should be any problems with that.

My recommendation: get rid of their crippled version.

Best regards,

Wolfgang Denk
