What's a "plb-pcix", and what's an example of a 440 SoCs which has it.IIRC that's the PCI(express) controller, which is not memory-mapped but inside the DCR address space, so accessed from the PLB.
This is the PCI(X) controller only, the PCIe(xpress) controller is (partially) implemented in sam460ex.c TYPE_PPC460EX_PCIE_HOST/"ppc460ex-pcie-host". The plb-pcix is the compatible name the fdt refers to. I only know of the 460EX that has it but probably other similar SoCs (like some 440 variants) also have this kind of PCI controller (according to #defines in U-Boot source but don't remember the details).
