ea6d8be153 Support setting FDT properties with optional values.
Fix a bug found and documented by Bartlomiej Sieka where the optional
value on "fdt set <path> <prop> [<val>]" wasn't optional.

=> fdt mknode / testnode
=> fdt print /testnode
testnode {
};
=> fdt set /testnode testprop
=> fdt print /testnode
testnode {
        testprop;
};

e125a2ffc2 Call ft_board_setup() from the bootm command.
In the patch titled "Create new fdt boardsetup command..." I removed the
call to ft_board_setup() from the routine fdt_chosen(), but I forgot
to add a direct call back into cmd_bootm.c

This fixes the oversight by adding the direct call to the bootm command.

fd61e55dd8 Create new fdt boardsetup command, fix bug parsing [] form of set values.
Previously ft_board_setup() was called by fdt_chosen() which was not
really correctly structured.  This splits ft_board_setup() out by creating
a new fdt boardsetup command.

Fix a bug when parsing fdt set command values which have the square
bracket form [00 11 22 33] - the length was updated incorrectly in when
parsing that form.

06e19a0770 For fdt_find_node_by_path(), handle the root path properly.
Also removes the special case root path detection in cmd_fdt.c since it
is no longer necessary.

1a861169bc Replace fdt_node_offset() with fdt_find_node_by_path().
The new name matches more closely the kernel's name, which is also
a much better description.

addd8ce830 Fix cmd_fdt line lengths, refactor code.
Break lines that were greater than 80 characters in length.
Move the fdt print and property parsing code to separate static functions
  to reduce coding clutter in the fdt_cmd handling body.

781e09ee6e Add a flattened device tree (fdt) command (1 of 2)
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.
