Subject: [PATCH 2/2] board: kontron: disable flash unlock all
Date: Wed, 9 Dec 2020 10:53:26 +0100 [thread overview]
Message-ID: <20201209095326.18514-2-michael@walle.cc> (raw)
In-Reply-To: <20201209095326.18514-1-michael@walle.cc>
Although the status register is protected by the hardware write
protection, there is a hardware jumper to disable that hardware write
protection. Thus if a user would set this jumper any u-boot start would
disable the write protection altogether.
Circumvent that by not disabling the write protection in the first
place.
