Subject: [PATCH 03/10] arm: imx: Drop custom lowlevel_init
Date: Thu, 22 Dec 2022 01:46:36 +0100 [thread overview]
Message-ID: <20221222004643.1013095-3-marex@denx.de> (raw)
In-Reply-To: <20221222004643.1013095-1-marex@denx.de>
The custom lowlevel_init implementation is no longer necessary, since
it is responsible for routing and trapping SErrors in U-Boot in EL2,
which is implemented in common code since commit:
6c7691edd55 ("armv8: Always unmask SErrors")
Signed-off-by: Marek Vasut <marex@denx.de>
