Add a new function to the eth_device struct for programming a network
controller's hardware address.

After all network devices have been initialized and the proper MAC address
for each has been determined, make a device driver call to program the
address into the device.  Only device instances with valid unicast addresses
will be programmed.

There are boards out there that do not have network support in
U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This
makes it desirable to be able to port network configuration (like
the IP address) to the Linux kernel.

We should not make the passing of the IP configuration to Linux
dependent on U-Boot features / settings.

For this, make getenv_IPaddr() global. This fixes build error

u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr'

on various architectures.

The random_port() is meant to be used by other net code, but without a

In the previous enetaddr refactoring, the assumption with commit 56b555a6
was that the eth layer would handle the env -> device enetaddr syncing.
This was not the case as eth_initialize() is called only once and the sync
occurs there.  So make sure the eth_init() function does the env -> device
sync with every network init.

On 04 Oct 2008 Pieter posted a dns implementation for U-Boot.

Here it is again - slightly modified & smaller:
  - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0)
  - README.dns is added
  - syntax is changed (now takes a third option, the env var to store
    the result in)
  - add a random port() function in net.c
  - sort Makefile in ./net/Makefile
  - dns just returns unless a env var is given
  - run through checkpatch, and clean up style issues
  - remove packet from stack
  - cleaned up some comments
  - failure returns much faster (if server responds, don't wait for
    timeout)
  - use built in functions (memcpy) rather than byte copy.

Declare new utility functions for converting between the environment
variables (eth*addr) and the binary MAC address representation.  This way
we can unify all the random places that already do this kind of thing.

The functions in question:
	eth_parse_enetaddr - "..." -> {...}
	eth_getenv_enetaddr - env -> {...}
	eth_setenv_enetaddr - {...} -> env

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get

Also remove all embedded "vim:" and "vi:" statements which hide

The purpose of this routine is receiving a single network frame, outside of
U-Boot's NetLoop(). Exporting it to standalone programs that run on top of
U-Boot will let them utilise networking facilities. For sending a raw frame
the already existing eth_send() can be used.

The direct consumer of this routine is the newly introduced API layer for
external applications (enabled with CONFIG_API).

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

  - Convert the CPM2 based functionality to use new CONFIG_CPM2
    option rather than a myriad of CONFIG_MPC8560-like variants.
    Applies to MPC85xx and MPC8260 boards, includes stxgp3 and sbc8560.
    Eliminates the CONFIG_MPC8560 option entirely.  Distributes the
    new CONFIG_CPM2 option to each 8260 board.
