Can you show me the complete command line for assembling arch/arm/mach-godbox/hi_pm_sleep.S into arch/arm/mach-godbox/hi_pm_sleep.o please? And also the output of gcc -v? My guess is that you are building GCC yourself have specified --with-float=softfp, but not specified the actual floating point architecture with --with-fpu= on the GCC configure line. See the documentation for -mfpu= in the GCC manuals to see what values are valid here (again guessing but you probably want --with-fpu=vfpv3 or --with-fpu=neon - but I don't know what architecture you are actually compiling for).
