uart/ns16550, drivers/pcie: add PCI(e) support A parallel PCI implementation ("pcie") is added with features for PCIe. In particular, message-signaled interrupts (MSI) are supported, which are essential to the use of any non-trivial PCIe device. The NS16550 UART driver is modified to use pcie. pcie is a complete replacement for the old PCI support ("pci"). It is smaller, by an order of magnitude, and cleaner. Both pci and pcie can (and do) coexist in the same builds, but the intent is to rework any existing drivers that depend on pci and ultimately remove pci entirely. This patch is large, but things in mirror are smaller than they appear. Most of the modified files are configuration-related, and are changed only slightly to accommodate the modified UART driver. Deficiencies: 64-bit support is minimal. The code works fine with 64-bit capable devices, but will not cooperate with MMIO regions (or MSI targets) that have high bits set. This is not needed on any current boards, and is unlikely to be needed in the future. Only superficial changes would be required if we change our minds. The method specifying PCI endpoints in devicetree is somewhat kludgey. The "right" way would be to hang PCI devices off a topological tree; while this would be more aesthetically pleasing, I don't think it's worth the effort, given our non-standard use of devicetree.
