...in preparation for improving the bootm command's handling of fdt blobs.
Also cleaned up some coding sloppiness.

Changed _fdt_check_header() to fdt_check_header() and made it part of
the interface - it is a useful routine.

Also did some asthetics cleanup to the include files (headers).

Modifications to the existing code to support the new fdt command.

The fdt command uses David Gibson's libfdt library to manipulate as well
as print the flattened device tree.  This patch is the new command,
the second part is the modifications to the existing code.

Enhanced the formerly private function _fdt_next_tag() to allow stepping
  through the tree, used to produce a human-readable dump, and made
  it part of the published interface.
Also added some comments.

Changes to David Gibson's original source to fit into u-boot's
environment.  No functionality changes.

This adds the applicable libfdt source files (unmodified) and a README
to explain where the source came from.

Now the DDR2 frequency is also 2*PLB frequency when 166MHz PLB
is selected.

Fix a bug in the auto calibration routine. This driver now runs
more reliable with the tested modules. It's also tested with
167MHz PLB frequency (667MHz DDR2 frequency) on the Katmai.

The "old" i2c commands (iprobe, imd...) are now compiled in again,

config option.

This patch adds some 4xx GPIO functions. It also moves some of the
common code and defines into a common 4xx GPIO header file.
