Subject: [PATCH v3 3/3] arm64: Kconfig: Enable usage of optimized memset/memcpy/memmove
Date: Wed, 11 Aug 2021 16:02:42 +0200	[thread overview]
Message-ID: <20210811140242.1942483-4-sr@denx.de> (raw)
In-Reply-To: <20210811140242.1942483-1-sr@denx.de>

This patch enables the use of the optimized memset(), memmove() &
memcpy() versions recently added on ARM64.

Signed-off-by: Stefan Roese <sr@denx.de>
