The arm-soc guys have a patch moving the platform-related config options
out into Kconfig.platforms, so I think you need to co-ordinate with them.

I'm fine with this.

Thanks for letting me know. I see that those patches are already merged
into for-next under arm-soc. I guess I should generate a new patch
series based on for-next and move this config option to Kconfig.platform?

Olof, any comment?

Yeah, please do that and send that series with arm@kernel.org on cc,
we'll apply it from there!

Note this patch series contains some iProc PCIe patches as per-requsite
that need to be applied before the ARCH_BCM_IPROC arm64 patch. Without
the PCIe patch, arm64 build out of defconfig would be broken.

Bjorn has acked the PCIe patches. I'll re-send the entire patch series
to you and arm@kernel.org and you can merge them there.

Thanks,

Ray
