From ce4835497c20991574fde492ab37ec666563d3e4 Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Thu, 17 Nov 2022 06:37:21 +0100 Subject: ARM: 9270/1: vfp: Add hwcap for FEAT_FHM Floating-point half-precision multiplication (FHM) is a feature present in AArch32 state for Armv8 and is represented by ISAR6.FHM identification register. This feature denotes the presence of VFMAL and VMFSL instructions and hence adding a hwcap will enable the userspace to check it before trying to use those instructions.
