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.

Adds a simple driver to access the 5x5 LED display found on BBC

that are specific to this display.

This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available. Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked. Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code. Another
simplification is that none of the offload capabilities of the
Ethernet device are used. The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.

This driver allows multiple drivers to share a common interrupt
line. This functionality is required on system that conform to the PC
interrupt structure. In the context of Zephyr this is needed for
SOC's that have their I/O IP blocks behind a PCI interface. Due to the
limited number of interrupt lines provided by the PCI interface
multiple IP blocks may be configured to share an interrupt line.
Drivers that share interrupts must be modified to *not* register their
own interrupt service routine as part of their configuration/initialization
but instead bind to the correct instance of this driver by name, then
register their interrupt service routine with this driver.
