From 5c3f5edbe0a1dff3f0b74f586f18f11e5c310f3c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 14 Oct 2014 15:05:57 +0200 Subject: [PATCH] ARM: realview: add flash devices to the PB1176 DTS This adds the flash memories and ROM to the PB1175 DTS file. The secure flash is marked as "disabled" by default so as to protect the user from overwriting the boot monitor.
