Currently it doesn't matter where the mdio nodes are placed, but with
power management support (i.e. when sleep = <> properties will take
effect), mdio nodes placement will become important: mdio controller
is a part of the ethernet block, so the mdio nodes should be placed
correctly. Otherwise we may wrongly assume that MDIO controllers are
available during sleep.

commit a969e76a (powerpc: Correct USB
support for GE Fanuc SBC610) introduced a fixup for NEC usb controllers.
This fixup should only run on GEF SBC610 boards.

Fixes Fedora bug #486511.

Most of the platforms were printing the size of the memory
in their show_cpuinfo implementations. This moves that to
the common show_cpuinfo, so that all 32-bit platforms will
now print the size of memory.  I also update the code
to deal with the fact that total_memory is now a phys_addr_t.

Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC
MPC8641D).

This patch adds support for the registers held in the devices main FPGA,
exposing extra information about the revision of the board through cpuinfo.

Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D).

A number of MPC8641D based route interrupts for on-board interrupts through
a FPGA based interrupt controller, which is chained with the
MPC8641D's mpic. This patch provides a basic driver to allow basic routing
of interrupts to the mpic.

Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC
MPC8641D).

Fixup to correctly reconfigure USB, provided by an NEC uPD720101, after
device is reset. This requires a set of chip specific registers in the
devices configuration space to be correctly written, enabling all ports
and switching the device to use an external 48-MHz Oscillator.

For many of the embedded boards, "model" and "Machine" are printing
the same thing; remove the redundant code and allow the generic
show_cpuinfo to print the model information.

Moved the pic initialization into its own common file and out of the board
code.  Also fixed the OF reference counting on the mpic node.

This adds support for the Wind River SBC8641D board, based
largely on the mpc86xx_hpcn support.  The biggest difference is
the lack of the Uli and the i8259 cascade, which simplifies things.
