From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Mon, 22 May 2017 05:17:25 -0600 Subject: [U-Boot] [PATCH 05/12] arm: Don't try to support CONFIG_ARMV7_LPAE on ARMv4T In-Reply-To: <20170522111732.11265-1-sjg@chromium.org> References: <20170522111732.11265-1-sjg@chromium.org> Message-ID: <20170522111732.11265-6-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de At present if CONFIG_ARMV7_LPAE is defined then mmu_setup() will use instructions which are invalid on ARMv4T. This happens on Tegra since it has an ARMv4T boot CPU. Add a check for the architecture version to allow the code to be built. It will not actually be executed by the boot CPU, but needs to compile.
