> Subject: [PATCH v3 1/1] build: add Graviton2(arm64) meson configuration
>
> Add meson build configuration for Graviton2 platform with 64-bit Arm
> Neoverse N1 cores. This patch makes the following changes to generic
> Neoverse N1 config:
>
> 1. increase lcore limit to 64
> 2. increase memory support to 1TB
> 3. remove +crc from -march as that is default when setting armv8.2
>
> For more information about Graviton2 platform, refer to:
