Platform: Raspberry Pi4

CPUInfo::get().has_fp16() returns true on RaspberryPi 4 (Cortex-A72). I believe, it should be false.

UPD: The issue is reproducible on 32-bit Debian 11 and not reproducible on 64-bit Debian 11.

Hi @alvoron

Please see the following patch fixing the problem: https://review.mlplatform.org/c/ml/ComputeLibrary/+/11242

Hope this helps

@morgolock I implemented the same approach in our code :)
As soon as the fix is included in ACL release I'll upgrade ACL version and remove our custom code.

Thank you.
