This reverts commit 882164a4a928bcaa53280940436ca476e6b1db8e.
Above commit added "SSB = y" dependency to the wrong symbol
SSB_DRIVER_PCICORE_POSSIBLE and prevented SSB_DRIVER_PCICORE from being
selected when needed. PCI core driver for core running in clienthost
mode is important for bus initialization. It's perfectly valid scenario
to have ssb built as module and use it with buses on PCI cards.
This fixes regression that affected all *module* users with PCI cards.

SSB_PCICORE_HOSTMODE protects MIPS specific code that calls not exported
symbols pcibios_enable_device and register_pci_controller. This code is
supposed to be compiled only with ssb builtin.

I think we also need to depend on PCI_DRIVERS_LEGACY.
See the other patch that floats around.

I believe it's already handled by SSB_PCIHOST_POSSIBLE's dependency on
PCI_DRIVERS_LEGACY.

That dependency seems to be wrong there.
Was it added among some other "let's just unbreak some random
build" change as well?
SSB_PCIHOST enables support for SSB on top of PCI. (Which is 99% of it
uses). I don't see how this uses the legacy API.
SSB_PCICORE_HOSTMODE enables PCI on top of SSB. Which is a MIPS corner
case. This uses the legacy MIPS API to register a PCI bus.

Yeah - that was commit 58eae1416b80 ("ssb: Disable PCI host for
PCI_DRIVERS_GENERIC").

Yeah the dependency would seem to be in the wrong place and should be on
SSB_PCICORE_HOSTMODE, in the same way as the bcma driver - commits
664eadd6f44b ("bcma: Fix 'allmodconfig' and BCMA builds on MIPS
targets") & 79ca239a68f8 ("bcma: Prevent build of PCI host features in
module").
Thanks,

I guess so.

I agree current dependency on PCI_DRIVERS_LEGACY doesn't make sense.
It doesn't break thing though, thanks to the || !MIPS. I'm going to
fix that up in separated patch.

This patch needs a "Reported-by: Matt Redfearn <[email protected]>".
Applying both patches leads to a correct configuration for PCI. I cannot test on
my present hardware, but the patches seem to be correct.

@Kalle: Please drop my patch from yesterday. This solution is much better.
