RP2350 FPU

[DatanoiseTV]

According to this it seems like it is using softmp mode for floating point operation for the RP2350.

SoftFP (soft floating point): Use hardware floating-point operations, but function calls pass parameters via general-purpose registers (compatible with non-FPU systems).

HardFP (hard floating point): Pass floating-point values in floating-point registers during function calls (which is faster but requires hardware FPU support).

So I wonder if it make sense to change it to read

-mfloat-abi=hard
