From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bryan O'Donoghue Date: Fri, 12 Jan 2018 14:52:19 +0000 Subject: [U-Boot] [PATCH 4/9] optee: Add optee_image_get_entry_point() In-Reply-To: <1515768744-25246-1-git-send-email-bryan.odonoghue@linaro.org> References: <1515768744-25246-1-git-send-email-bryan.odonoghue@linaro.org> Message-ID: <1515768744-25246-5-git-send-email-bryan.odonoghue@linaro.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add a helper function for extracting the least significant 32 bits from the OPTEE entry point address, which will be good enough to load OPTEE binaries up to (2^32)-1 bytes. We may need to extend this out later on but for now (2^32)-1 should be fine. Signed-off-by: Bryan O'Donoghue Cc: Harinarayan Bhatta Cc: Andrew F.
