This reverts commit e002474158d1054a7a2ff9a66149384c639ff242.
Commit e002474158d1 ("pci: pci-uclass: Dynamically allocate the PCI regions") changes 'struct pci_controller'.regions from pre-allocated array of regions to dynamically allocated, which unfortunately broken lots of boards that still use the non-DM PCI driver.
We may update every non-DM PCI board codes to do the dynamical allocation of PCI regions but that's a lot of work (e.g.: almost all Freescale PowerPC boards are broken now and need to be fixed). Let's do the easy way.
No one has noticed since July, apparently. I think it would be better to disable PCI on these boards, until either someone migrates them or they are removed. The PCI deadline was about 18 months ago.
Tom, do you know the situation here?
I want to hear what Priyanka has to say, as there's been an effort a few times on NXP's part to remove boards they don't want to maintain anymore.
Outside of that, I do keep meaning to, but not quite finding the time to, pick a random well-past migration deadline, make it fatal, and then go start removing boards. I think I'll go pick a not-PCI (as some number of PowerPC ones will fail, and that's not as interesting until Priyanka can chime in) one right now and see what fails there.
