Subject: [PATCH v1 2/5] board_init: Use memset_simple() in board_init_f_init_reserve()
Date: Fri,  6 Aug 2021 15:38:40 +0200	[thread overview]
Message-ID: <20210806133843.3642916-3-sr@denx.de> (raw)
In-Reply-To: <20210806133843.3642916-1-sr@denx.de>

board_init_f_init_reserve() is called very early in the boot process,
before the caches are enabled. Because of this, the optimized memset()
version can't be used here on ARM64. With this patch, the simple memset
version memset_simple() is used here instead.
