Linux understands "host" (default), "peripheral" and "otg" (broken).
Though, U-Boot doesn't restrict dr_mode variable to these values (think
of renames in future).

These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob.  The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).

The only board that enables these is the stxxtc and they don't appear
to be used by linux.

Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob and
perform the actual upload.  Add command-line command "qe fw" to take a firmware
blob in memory and upload it.  Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware.  Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

Implement a suggestion by Scott Wood to make the /chosen handling fine
grained.  Don't overwrite pre-existing properties on a per-property basis,
so if /chosen exists but a necessary /chosen/property doesn't, it gets
created.  If a /chosen property exists, it is NOT overwritten unless the
"force" flag is true.

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.

bracket form [00 11 22 33] - the length was updated incorrectly in when

What was suppose to be a stack variable was declared as a pointer,
  overwriting random memory.
Also moved the libfdt.a requirement into the main Makefile.  That is
  The U-Boot Way.

In bootm, create the "/chosen" node only if it doesn't already exist
  (better matches the previous behavior).
Update for proper reserved memory map handling for initrd.

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