(type 1 and type 2) as well as leaf devices (type 0). In particular,
this allows the existing PCI bus logic to save and restore capability
registers such as MSI and PCI-express work for bridge devices rather than
requiring that code to be duplicated in bridge drivers. It also means
that bridge drivers no longer need to save and restore basic registers
such as the PCI command register or BARs nor manage powerstates for the
bridge device.
While here, pci_setup_secbus() has been changed to initialize the 'sec'
and 'sub' fields in the 'secbus' structure instead of requiring the pcib
and pccbb drivers to do this in the NEW_PCIB + PCI_RES_BUS case.

could be either MII_MEDIA_10_T or MII_MEDIA_10_T_FDX, which are 1 and 2,
accordingly. Neither matches a valid BMCR value. My guessing is that this
write is harmless, since later mii_phy_setmedia() would write a proper
value there.
The code is here since the initial checkin. Note that case IFM_100_TX has

two cases into one, always writing there BMCR_ISO.

This is inspired by something in jhb's NUMA IRQ allocation patchset.
However, the tricky bit here is that the PXM lookup for a node may
fail, requiring a lookup on the parent node. So if it doesn't
exist, don't fail - just go up to the parent. Only error out of the
lookup is the ACPI lookup returns an error.

This is only the minimum set of files needed to boot in qemu. As such it is
missing a few things.
The bus_dma code is currently only stub functions with a full implementation
from the development tree to follow.
The gic driver has been copied as the interrupt framework is different. It
is expected the two drivers will be merged by the arm intrng project,
however this will need to be imported into the tree and support for arm64
would need to be added.
This includes code developed by myself, SemiHalf, Ed Maste, and Robin
Randhawa from ARM. This has been funded by the FreeBSD Foundation, with
early development by myself in my spare time with assistance from Robin.

Enable two finger scrolling by default and disable the edge scrolling if
the touchpad has no physical zone for it. Disable directional scrolling
by default to avoid using extended buttons as scroll buttons.
Add support for ClickPad. On Lenovo laptops, this is the button
reported when one presses the touchpad.
While there, fix a problem where the extended buttons were not reporting
the button release event correctly: we need to save the state of the
buttons and report it to sysmouse until we receive a packet from the
touchpad indicating the button has been released. This makes it
possible to use an extended button to resize a window. On Lenovo
laptops, the major buttons are actually reported as extended buttons.

This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.
This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.
