From 1ca0992ef1eef332496c6e0496a4f49f31ab1c23 Mon Sep 17 00:00:00 2001 From: Trilok Soni Date: Thu, 21 Apr 2016 15:46:42 -0700 Subject: [PATCH] lib: memtest: Add MEMTEST_ENABLE_DEFAULT option As of now memtest remains disabled until we specify the patterns through the kernel command line. Some platforms have two different configurations files (one for debug and another for product) which can use the configuration option to enable the memtest by default (in the debug configuration file).
