I think you want to add a line

    depends on ARCH_LAYERSCAPE || ARCH_MXC || COLDFIRE ||
FSL_SOC_BOOKE || COMPILE_TEST

(or PPC instead of FSL_SOC_BOOKE?)
so the question doesn't pop up when compiling a kernel for a system
that cannot have a Freescale FlexCAN IP block.

Back in 2018 Pankaj Bansal replaced the "depends on ARM || PPC" by "OF
&& HAS_IOMEM", see:

| 0f8af56f74cd can: flexcan: enable flexcan for all architectures

So I think there won't be too many configs where the oldconfig question
would pop up.

Marc
