Subject: [PATCH 0/4] MIPS: Loongson64: Use logic_pio 

To add I/O ports for PCI host bridge via devicetree, we have to use
logic_pio mechanism.
That would require convert I/O ports into virt memory map.

Jiaxun Yang (4):
  MIPS: Massage address spaces headers
  MIPS: Introduce PCI_IO_VMMAP
  lib: logic_pio: Introduce MMIO_LOWER_RESERVED
  MIPS: Loongson64: Enable PCI_IO_VMMAP
