-/**
- * kbase_get_platform_logic_tile_type -  determines which LogicTile type
- * 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 determines which LogicTile type is used by the platform by
- * reading the HBI value of the daughterboard which holds the LogicTile:
- *
- * 0x217 HBI0217 Virtex-6
- * 0x192 HBI0192 Virtex-5
- * 0x247 HBI0247 Virtex-7
- *
- * Return: HBI value of the logic tile daughterboard, zero if not accessible
