add 'miitool' command to view media-independent interface status ...

This command is based on the 'mii-diag' and 'mii-tool'
Unix utilities, but it lacks routines to manipulate
MII state (e.g. reset MII, restart autonegotiation
or force MII mode).

This version of the 'miitool' command has no GbE support,
but we can upgrade it in the future. The GbE support
patch for generic 'mii-tool' is here
http://ftp.debian.org/debian/pool/main/n/net-tools/net-tools_1.60-24.2.diff.gz

EXAMPLE:

barebox:/ miitool -vv /dev/phy0

Add in-system barebox update infrastructure ...

Currently in-system update means to write an arbitrary file to
an arbitrary device. There is no sanity check if the flashed image
is of the right type or will fit onto the device. Furthermore some
SoCs need a special preparation step for their images before
flashing them.

This adds a barebox in-system update infrastructure. Boards can
register update handlers which know how to make the board bootable.
The available handlers can be listed to be able to select one,
different force levels give the user the chance to know it better.

This adds some basic commands to manupulate clocks on the command

The commands work based on the clock name, otherwise they behave like
the Linux Kernel C functions. clk_dump will dump the clocktree to the
console.

net: Add tftp command which uses the new tftp code ...

Traditionally tftp is a command of its own. Since we can
mount tftp as a filesystem we have duplicated the tftp code, the old
code is used by the tftp command, the new by the filesystem support.
This adds a tftp command based on the filesystem support to preserve
backward compatibility. This allows us to remove the old tftp support
in the next step.
