[U-Boot] soft vs. hard float
It looks U-Boot is generally built using soft float. I need hard-float in my system. Is this a general enough need that it'd make sense to have a CONFIG_SYS_HARD_FLOAT to enable this option?
I made a quick update for mpc85xx (guarded by CONFIG_SYS_HARD_FLOAT) and I seem to be running fine. Thanks,
Dean

This makes no sense. U-Boot does not use any FP operations at all.

U-Boot does not (and will not) support FP. If you want to do number crunching, then start an OS.
Best regards,
