Re: [U-Boot] Whose responsibility is it to enable FPU?

U-Boot does not need nor use the FPU, so enabling it would not help you in any way.

It may not need it, but enabling it in u-boot did actually fix the problem. I just called the fpu_enable function in the u-boot post code.

Linux will do it's own settings, so this is where you need to look for your incorrect configuration settings (incorrect CPU description in the DT?).

Okay, thanks. I'll try to find out more about how Linux sets this up.

By the way, my dts file has

cpu@0 { device_type = "cpu"; model = "PowerPC,440EPx";
