Dear Scott Wood,

On cores that have FP (at least those that support the FPU POST, and which are currently having problems), use hard float, enable MSR[FP] or equivalent, and let GCC use FP for various tasks if it wants. This shouldn't involve much more complexity than adding a small amount of init, which you'd need for the POST anyway.
On cores that don't have FP, use soft float, and don't include the FPU POST code. This should not be any different than today, except for adding another compiler flag that depends on the build target.
And why exactly should we do all this,
To fix the FPU POST build errors.
Do you have a simpler way to do this? Note that for any board that doesn't currently have a problem, "all this" means no change at all.
And for those that do have a problem, the change is pretty minor.
given the fact that there are no intentions to work with floating point data in U-Boot?
FPU POST doesn't count?
Or are you saying FPU POST should be removed?
