+/*
+ * Default boot environment for Samsung Platform
+ * For board config file:
+ * - add: #include <samsung/platform_boot.h>
+ * - add PLATFORM_BOOT_INFO to CONFIG_EXTRA_ENV_SETTINGS
+ * - add checkboard macro to CONFIG_EXTRA_ENV_SETTINGS
+ *   e.g.:
+ *   #define CONFIG_EXTRA_ENV_SETTINGS \
+ *           PLATFORM_BOOT_INFO \
+ *           "checkboard=\0" \
+ *            ...
+ * - add: #define CONFIG_BOOTCOMMAND        "run autoboot"
+ *
+ * The above changes may need undef the existing configs.
+ * #undef CONFIG_BOOTCOMMAND
+ * #undef CONFIG_EXTRA_ENV_SETTINGS
+ * Note: Add the #undef before the new definitions.
