I think also that there is no choice but to have a float option for ARM C, either 'soft' or 'hard' (or 'softfp', actually, which is 'hard' with the 'soft' calling conventions), because the C compiler does not allow 'no floats', and anyway the C language *requires* to have some sort of float support. Actually if you don't specify any float option, the C toolchain will choose one, which is just the same in the end: *some* float option is chosen. And since some option must be chosen, I prefer that U-Boot make the explicit decision, and choose soft float for the reasons I already exposed.
