+		In the past, pinmap files included GPIO_SPEED_xxxMhz. These speed
+		settings should have come from the board.h as it describes the wiring
+		of the SoC to the board. The speed is really slew rate control and
+		therefore is related to the layout and can only be properly set
+		in board.h.
+
+		STM32_USE_LEGACY_PINMAP is provided, to allow lazy migration to
+		using pinmaps without speeds. The work required to do this can be aided
+		by running tools/stm32_pinmap_tool.py. The tools will take a board.h
+		file and a legacy pinmap and outut the required changes that one needs
