1.  Add README.txt with upgrade instructions as well as license info
    and governance.
2.  Add FREEBSD-Xlist to prune the distribution.
3.  Remove files & directories not used by FreeBSD.

Adds gpioiic.4 and gpioled.4 man pages.  Moves some of the information that
was previously available on gpio.4 to their respectives pages.  Add the
cross references on gpioctl.8.

As all the IIC controllers on system uses the same 'iichb' prefix we cannot
rely only on checking the device unit to indentify the BSC unit we are
attaching to.  Make use of the device base address to identify our BSC unit.

Fix a typo on a comment in ofw_bus_if.m, the default method will return -1
when a node doesn't exist.

Just disable recoding support in libsmb if built WITHOUT_ICONV.
Fix gpiobus to return BUS_PROBE_GENERIC insted of BUS_PROBE_SPECIFIC (0) so
it can be overriden by its OFW/FDT version.

Give a chance for GPIO devices that implement the device_identify method to
attach.

Actually add IOMMU domain to the list of known mappings. This fixes a bug
where multiple devices in the same IOMMU domain would be allocated
conflicting mappings unless they also shared a DMA tag.

MFC after:	3 days
Following the approach with ACPI DMAR on x86, split IOMMU handling into
a variant PCI bus instead of trying to shoehorn it into the PCI host bridge
adapter. Besides matching better the architecture on other platforms, this
also allows systems with multiple partitionable endpoints per PCI host
bridge to work correctly.
Noted that the stripe_size argument was not being displayed in the usage
message

Update LLDB to upstream r194122 snapshot

ludes minor changes relative to upstream, for compatibility with
FreeBSD's in-tree LLVM 3.3:

- Reverted LLDB r191806, restoring use of previous API.
- Reverted part of LLDB r189317, restoring previous enum names.
- Work around missing LLVM r192504, using previous registerEHFrames API
  (limited functionality).
- Removed PlatformWindows header include and init/terminate calls.

Eliminate the gratuitous use of mmap(2) flags from the implementation
of kern_shmat().  Use a simpler approach to determine whether to pass
VMFS_NO_SPACE or VMFS_OPTIMAL_SPACE to vm_map_find().
Add support for Freescale Vybrid Family VF600 heterogeneous
ARM Cortex-A5/M4 SoC (M4 core is not used in this work).

Support includes device drivers for:
- NAND Flash Controller (NFC)
- USB Enhanced Host Controller Interface (EHCI)
- General-Purpose Input/Output (GPIO)
- Universal Asynchronous Receiver/Transmitter (UART)

Also supported:
- Generic Interrupt Controller (GIC)
- MPCore timer
- ffec ethernet driver

Revert r257715.  This breaks the case where devd isn't running.  The
real solution to this is still being discussed and probably won't look
quite like this.
Add an -s option that specifies a path to an alternate etcupdate.sh script
to test.  This allows a non-installed version of the script to be tested
more easily.
Sort option flags and fix the width of the options list.  This is a purely
mechanical change, no content changes.
