This configuration builds an image for the Compute Module 5 IO Board.

Important: The debug UART header is not assembled on the Compute Module
5[1].

	2.23. Debug UART

        Space is provided for the user to fit a debug UART connector.
        This connector provides the same functionality as Raspberry Pi
        5. The connector is a three-pin 1mm pitch JST-SH connector, Part
        number BM03B-SRSS-TB. The signals are replicated on the bottom
	as test points.
