No, this is not possible (at least not with reasonable efofort and
resonable code).

That's not surprise. When testing, I build U-Boot for  *all*  PowerPC
systems with the same toolchain, usually using a ppc_8xx- or ppc_4xx-
configuration. All these images buil without problems, and more, they
even  run fine on the target systems. U-Boot usually does not include
any code which depends on such specific CPU features.

Best regards,

Wolfgang Denk
