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.
This fixes:
ERROR: "pcibios_enable_device" [drivers/ssb/ssb.ko] undefined!
ERROR: "register_pci_controller" [drivers/ssb/ssb.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:92: __modpost] Error 1

PCIcore hostmode operation (external PCI bus).
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?
Yeah - that was commit 58eae1416b80 ("ssb: Disable PCI host for
PCI_DRIVERS_GENERIC").
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 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,
Matt
