This patch adds a generic driver for SJA1000 chips on the OpenFirmware
platform bus found on embedded PowerPC systems. You need a SJA1000 node
definition in your flattened device tree source (DTS) file similar to:
can@3,100 {
compatible = "nxp,sja1000";
reg = <3 0x100 0x80>;
interrupts = <2 0>;
interrupt-parent = <&mpic>;
nxp,external-clock-frequency = <16000000>;
};

As discussed on the netdev mailing list, the member "base_addr" of
"struct net_device" should not be (mis)used to store the virtual
address to the SJA1000 register area. According to David Miller,
it's only use is to allow ISA and similar primitive bus devices to
have their I/O ports changed via ifconfig. The virtual address is
now stored in the private data structure of the SJA1000 device and
the callback functions use "struct sja1000_priv" instead of the
unneeded "struct net_device".

The CAN network device driver interface provides a generic interface to
setup, configure and monitor CAN network devices. It exports a set of
common data structures and functions, which all real CAN network device
drivers should use. Please have a look to the SJA1000 or MSCAN driver
to understand how to use them. The name of the module is can-dev.ko.
Furthermore, it adds a Netlink interface allowing to configure the CAN
device using the program "ip" from the iproute2 utility suite.

This patch adds the virtual CAN bus (vcan) network driver.
The vcan device is just a loopback device for CAN frames, no
real CAN hardware is involved.
