      pci root complex: support for tile architecture · f02cbbe6
      Chris Metcalf 提交于
      This change enables PCI root complex support for TILEPro.  Unlike
      TILE-Gx, TILEPro has no support for memory-mapped I/O, so the PCI
      support consists of hypervisor upcalls for PIO, DMA, etc.  However,
      the performance is fine for the devices we have tested with so far
      (1Gb Ethernet, SATA, etc.).
      
      The <asm/io.h> header was tweaked to be a little bit more aggressive
      about disabling attempts to map/unmap IO port space.  The hacky
      <asm/pci-bridge.h> header was rolled into the <asm/pci.h> header
      and the result was simplified.  Both of the latter two headers were
      preliminary versions not meant for release before now - oh well.
      
      There is one quirk for our TILEmpower platform, which accidentally
      negotiates up to 5GT and needs to be kicked down to 2.5GT.
