Subject: [PATCH v2 2/5] board: sama5d27_som1_ek: Modify load addresses
Date: Mon, 16 Aug 2021 14:25:40 +0200 [thread overview]
Message-ID: <20210816122543.33532-3-clement.leger@bootlin.com> (raw)
In-Reply-To: <20210816122543.33532-1-clement.leger@bootlin.com>
When using OP-TEE, address range [0x20000000 - 0x22000000] is reserved.
This modification allows to have a system which always work even when
OP-TEE is present.
