Dear Timur Tabi,

I think you misunderstand. I'm not saying that we should use FP instructions in U-Boot. I'm saying that since we *don't* use FP instructions in U-Boot, we can just turn on hard-float and avoid any incompatibility with CONFIG_POST_FPU, because all of U-Boot will then be compiled with hard-float.
If we let him, GCC would generate FP instructions in a number of places where you don't expect them, even whithout any FP variables or explicit FP operations in the whole code C or assembler input.
Best regards,
