Rong Zhang 32ec465103 MIPS: Loongson2ef: Use pcibios_align_resource() to block io range ... Loongson2ef reserves io range below 0x4000 (LOONGSON_PCI_IO_START) while ISA-mode only IDE controller on the south bridge still has a hard dependency on ISA IO ports. The reservation was done by lifting loongson_pci_io_resource.start onto 0x4000. Prior to commit ae81aad5c2 ("MIPS: PCI: Use pci_enable_resources()"), the arch specific pcibios_enable_resources() did not check if the resources were claimed, which diverges from what PCI core checks, effectively hiding the fact that IDE IO resources were not properly within the resource tree. After starting to use pcibios_enable_resources() from PCI core, enabling IDE controller fails: pata_cs5536 0000:00:0e.2: BAR 0 [io 0x01f0-0x01f7]: not claimed; can't enable device pata_cs5536 0000:00:0e.2: probe with driver pata_cs5536 failed with error -22 MIPS PCI code already has support for enforcing lower bounds using PCIBIOS_MIN_IO in pcibios_align_resource() without altering the IO window start address itself. Make Loongson2ef PCI code use PCIBIOS_MIN_IO too.
