From 4d94dfa0594260245813ea150e276908cc677199 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 10 Jul 2014 22:23:27 -0600 Subject: [PATCH] sandbox: Set up global data before board_init_f() At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.
