Add this dependency to the Kconfig file to fix the following
build error when CONFIG_INTEGRATOR_AP is set but CONFIG_PCI
is not:
LD init/built-in.o
arch/arm/mach-integrator/built-in.o: In function `ap_map_io':
integrator_cp.c:(.init.text+0x570): undefined reference to `pci_v3_early_init'
make[1]: *** [vmlinux] Error 1
make: *** [sub-make] Error 2

No, integrator does not require PCI, so this needs to be fixed by other
means, such as finding out how the breakage was introduced, and fixing
the real cause of this regression.

You are right, just found out that this introduces a recursive
dependency while compiling another config:
arch/arm/Kconfig:1403:error: recursive dependency detected!
arch/arm/Kconfig:1403: symbol PCI depends on MIGHT_HAVE_PCI
arch/arm/Kconfig:108: symbol MIGHT_HAVE_PCI is selected by ARCH_INTEGRATOR_AP
arch/arm/mach-integrator/Kconfig:5: symbol ARCH_INTEGRATOR_AP depends on PCI
So when integrator does not depend on PCI this diff is more appropriate?

Yes.

And can you please create and send a proper patch with this
content to arm at kernel.org and the mailing list on CC, with
a request for the ARM SoC maintainers to apply it directly
as a fix?
You might as well add Cc: stable at vger.kernel.org as well.
Yours,
Linus Walleij

Will do, thanks for your review.

Okay, sorry, forgot about this one. But my compile-tests kindly reminded
me and I sent the patch out again now :)
