From 8cda413b9b13e4bbb636d2d6151da9902de35fa2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Thu, 8 Jan 2015 10:11:40 +0100 Subject: [PATCH] Nokia RX-51: Do not call secure PPA routine on non secure devices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 41623c91b09a0c865fab41acdaff30f060f29ad6 u-boot running in qemu is crashing in function do_omap3_emu_romcode_call(). RX-51 board uses this function for Cortex-A8 errata 430973 workaround (Set IBE bit in ACR) which is needed only on real secure device and not in qemu. This board patch just disable calling secure PPA routine on non secure devices. Qemu implements GP device and with this patch u-boot is working in qemu again.
