Shouldbe working fine. The ELDK "ppc_4xxFP" packages do the same.

This is no reason for any problems. As mentioned above, ELDK in the
ppc_4xxFP configuration (and some others) support hardware FP as
well, but works fine with U-Boot. After all, U-Boot is
self-contained.

3) fix your toolchain.

A 4xx FP toolchain is a perfectly good idea - that's why we support
such a configuration in ppc_4xxFP with the ELDK. But it doesn't need
any changes to U-Boot.

I see that Microsoft's campaign to destroy all knowledge of any
operating environment but its own environment-of-the-year has
succeeded in creating a generation of users who don't understand the
concept of a shell...
