Subject: [U-Boot] [PATCH v4 12/14] jetson-tk1: Add PSCI configuration options and reserve secure code
Date: Fri, 27 Feb 2015 14:28:11 +0100	[thread overview]
Message-ID: <8329f6ba8867465f3bdd757673f2a10e3d97a71f.1425043693.git.jan.kiszka@siemens.com> (raw)
In-Reply-To: <cover.1425043693.git.jan.kiszka@siemens.com>

From: Ian Campbell <ijc@hellion.org.uk>

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.
