I guess I must be misunderstanding that comment - there are many many
examples of boards adding properties to nodes that describe the SoC. For
example, the GPIOs used by SDHCI controllers, board-specific max clock
rates for SDHCI or I2C controllers, pinmux configuration properties, to
name just a few.
