Subject: [PATCH 4/4] arm64: head: fix code comments in set_cpu_boot_mode_flag
Date: Tue, 18 May 2021 18:14:05 +0800	[thread overview]
Message-ID: <20210518101405.1048860-5-aisheng.dong@nxp.com> (raw)
In-Reply-To: <20210518101405.1048860-1-aisheng.dong@nxp.com>

Up to here, the CPU boot mode can either be EL1 or EL2.
Correct the code comments a bit.
