+ * is used by Versatile Express
+ *
+ * When platform_config build parameter is specified as vexpress, i.e.,
+ * platform_config=vexpress, GPU frequency may vary dependent on the
+ * particular platform. The GPU frequency depends on the LogicTile type.
+ *
+ * This function is called by kbase_common_device_init to determine
+ * which LogicTile type is used by the platform by reading the HBI value
+ * of the daughterboard which holds the LogicTile:
+ *
+ * 0x192 HBI0192 Virtex-5
+ * 0x217 HBI0217 Virtex-6
+ * 0x247 HBI0247 Virtex-7
+ *
+ * Return: HBI value of the logic tile daughterboard, zero if not accessible
