- Copy stable/10@285827 to releng/10.2 in preparation for 10.2-RC1
builds.
- Update newvers.sh to reflect RC1.
- Update __FreeBSD_version to reflect 10.2.
- Update default pkg(8) configuration to use the quarterly branch.[1]

MFC r270945:

Rename OF_xref_phandle() to OF_node_from_xref() and add a new function
that provides the inverse translation, OF_xref_from_node().

MFC r261410

Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

MFC r257991, r257992, 257993, 258504

r257991:
Consolidate Apple firmware hacks and improve them by switching on the
presence of mac-io devices in the tree, which uniquely identifies Apple
hardware.

r257992:
Allow OF_decode_addr() to also be able to map resources on big-endian
devices. To this end, make PCI device detection rely on the device_type
field rather than name, as per the standard.

r257993:

Make tsec work with the device tree present on the RB800. The previous code
assumed that the MDIO bus was a direct child of the Ethernet interface. It
may not be and indeed on many device trees is not. While here, add proper
locking for MII transactions, which may be on a bus shared by several MACs.

r258504:

Save and restore the trap vectors when doing OF calls on pSeries machines.

It turned out that on pSeries machines the call into OF modified the trap
vectors and this made further behaviour unpredictable.

With this commit I'm now able to boot multi user on a network booted
environment on my IntelliStation 285. This is a POWER5+ machine.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Respect phy-handle property in Ethernet nodes of the device tree.

This lets specify whereabouts of the parent PHY for a given MAC node
(and get rid of ugly kludges in mge(4) and tsec(4)).

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
Discussed with: jhb
- Also while at it, use __FBSDID.

Don't use the MAC address in the device tree if it's all zeroes
(i.e. 00-00-00-00-00-00). Use the currently programmed address
instead.

While here, simplify the function.

Convert Freescale PowerPC platforms to FDT convention.

The following systems are affected:

- MPC8555CDS
- MPC8572DS

This overhaul covers the following major changes:

- All integrated peripherals drivers for Freescale MPC85XX SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).

- This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
QUICC, UART, CFI.

- Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
ocpbus(4) driver, which was based on hard-coded config data.

Note that world for these platforms has to be built WITH_FDT.
