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.

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)).

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.

- polling
- jumbo frames
- multicast
- VLAN tagging
The enhanced version of the chip (eTSEC) can also take advantage of:
- TCP/IP checksum calculation h/w offloading

Split the driver into the core functionality part (sys/dev/tsec/if_tsec.c) and
the bus attachment (sys/dev/tsec/if_tsec_ocp.c).
This lets better integrate and maintain the driver in other environments with
different attachment abstractions (there is at least one other FreeBSD port --
MPC83xx -- which uses this TSEC driver, but with different local bus model
i.e. some OF derivative). While there, clean up and fix minor cosmetics.

TSEC is the MAC engine offering 10, 100 or 1000 Mbps speed and is found on
different Freescale parts (MPC83xx, MPC85xx). Depending on the silicon version
there are up to four TSEC units integrated on the chip.
This driver also works with the enhanced version of the controller (eTSEC),
which is backwards compatible, but doesn't take advantage of its additional
features (various off-loading mechanisms) at the moment.
