Subject: [PATCH 01/27] ARM: fix scratch mem position with OP-TEE
Date: Fri, 12 May 2023 13:09:42 +0200 [thread overview]
Message-ID: <20230512111008.1120833-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230512111008.1120833-1-s.hauer@pengutronix.de>
OP-TEE is placed right below the end of memory, so the scratch space
has to go below it.
