But we also do not have any need for FP operations either. It would just add to the complexity (and to the memory foot print, especially on systems without FPU where we would have to provide soft-float libraries, plus eventually variantes for SPEv1 and SPEvv2 and whatever - not to mention that tghis will be needed for all the non-PPC architectures as well).
I think you misunderstand. I'm not saying that we should use FP instructions in U-Boot. I'm saying that since we *don't* use FP instructions in U-Boot, we can just turn on hard-float and avoid any incompatibility with CONFIG_POST_FPU, because all of U-Boot will then be compiled with hard-float.
