Subject: [Buildroot] [PATCH 02/28] configs/acmesystems_acqua_a5_512mb_defconfig: enable NEON/VFPV4 FPU strategy
Date: Tue, 18 Jan 2022 11:43:12 +0100	[thread overview]
Message-ID: <20220118104338.2081259-3-giulio.benetti@benettiengineering.com> (raw)
In-Reply-To: <20220118104338.2081259-1-giulio.benetti@benettiengineering.com>

As pointed by SAMA5D2 Datasheet[1]:
```
The Cortex-A5 NEON Media Processing Engine (MPE) extends the Cortex-A5
functionality to provide support for the ARM v7 Advanced SIMD v2 and
Vector Floating-Point v4 (VFPv4) instruction sets.
```

So let's enable VFPV4/NEON FPU strategy instead of the default VFPV4-D16.
