Subject: [U-Boot] [PATCH 1/2] imx: mx8m: add memory mapping for CAAM and TCM
Date: Wed, 14 Nov 2018 17:55:28 +0100 [thread overview]
Message-ID: <20181114165529.6563-2-gary.bisson@boundarydevices.com> (raw)
In-Reply-To: <20181114165529.6563-1-gary.bisson@boundarydevices.com>
Otherwise can't boot the M4 core as it is impossible to load its
firmware into the TCM memory.
