From ad21fc4faa2a1f919bac1073b885df9310dbc581 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 6 Feb 2017 16:31:57 -0800 Subject: arch: Move CONFIG_DEBUG_RODATA and CONFIG_SET_MODULE_RONX to be common There are multiple architectures that support CONFIG_DEBUG_RODATA and CONFIG_SET_MODULE_RONX. These options also now have the ability to be turned off at runtime. Move these to an architecture independent location and make these options def_bool y for almost all of those arches.
