Please read this message again, and carefully.

I never mentioned glibc. Nor is it mentioned in  the  error  message.
The  library  in  question  is  "libgcc.a", where the compiler itself
(GCC) provides utility functions  (like  here  divsi3  to  perferm  a
signed division operation).

I repeat: Your  compiler  libraries  are  built  using  hardware  FP,
whereas u-boot uses software FP.

In other words: your toolchain is not configured as you expected.

Best regards,
