From af607747def54d8f76d2509c1394587da5d9bdfd Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Sat, 30 May 2009 13:56:13 +0100 Subject: RealView: Allow access to the secure flash memory block on PB1176 This patch adds a Kconfig option for specifying whether Linux will only be run in secure mode on the RealView PB1176 platform. Enabling it will make the secure flash memory block (64MB @ 0x3c000000) available to Linux.
