The Kconfig symbols are a bit confusing here: CONFIG_SOC_NUC900
controls the compilation of the soc_device driver, but I guess
what you actually mean here is CONFIG_SOC_NUC970, which is the
support for the actual chip.

Maybe rename the former to something less confusing and change
this to CONFIG_SOC_NUC970?

You are right, it should _NUC970. Many thanks!

Ideally, this should just go away once we use SPARSE_IRQ.

This platform also can use SPARSE_IRQ? this just a simple irq map and no 
more irq number in this Soc.
