1// Targets Cortex-A7/A8/A9 processors (ARMv7-A) running NuttX with hardware floating point
2//
3// This target assumes that the device has a FPU (Floating Point Unit)
4// and will use hardware floating point operations. This matches the NuttX EABI
5// configuration with hardware floating point support.
