From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jan Kiszka Date: Mon, 13 Apr 2015 06:48:20 +0200 Subject: [U-Boot] [PATCH v6 15/15] jetson-tk1: Add PSCI configuration options and reserve secure code In-Reply-To: References: Message-ID: <2366351e8fd7b6b7a8b8b078b3722ab547d3615a.1428900500.git.jan.kiszka@siemens.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Ian Campbell The secure world code is relocated to the MB just below the top of 4G, we reserve it in the FDT (by setting CONFIG_ARMV7_SECURE_RESERVE_SIZE) but it is not protected in h/w. See next patch.
