+/**
+ * @file
+ * @brief Wrapper to call board level initialization routine
+ *
+ * FileName: arch/arm/boards/omap/platform.S
+ *
+ * board_init_lowlevel is defined here. This calls board_init which
+ * is linked to the binary - the board_init only has a SRAM stack.
+ * so it needs to be careful about the usage of global variables
+ * and the likes. Enabled only if CONFIG_MACH_DO_LOWLEVEL_INIT is
+ * defined
