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
Probably the real reason behind that was to enable it on ARM64
(more specifically ARCH_LAYERSCAPE || ARCH_MXC).
Probably. What about the original proposed change: "(OF || M5441x) && HAS_IOMEM"?
Yeah, the Flexcan might pop up on RISC-V, too.
But any new platforms should use OF.
Given the Flexcan is probably present on more than just M5441x,
I'd go for:
depends on OF || COLDFIRE || COMPILE_TEST
depends on HAS_IOMEM
So I think there won't be too many configs where the oldconfig question
would pop up.
Now it will, as Mr. Torvalds' main machine does not satisfy "ARM || PPC"
or "OF && HAS_IOMEM", but does "HAS_IOMEM" ;-)
IC, that would be one question too much :)
I do doubt he has CONFIG_CAN enabled ;-)
