The old output of "help" was just producing a long list, that usually
scrolled of the screen (even on a X11 terminal). This list is more
compact, and also sorted by groups.
The old output format (plus grouping) is now available with 'help -v'.
Example:
Information commands:
?, devinfo, help, iomem, meminfo, version
Boot commands:
boot, bootm, go, loadb, loads, loadx, loady, saves, uimage
...

Currently the bootm code uses of_fix_tree to apply the fixups
to the devicetree given on the command line. This function assumes
that there is enough space for the fixups available. Also on ARM
we have to make sure the tree does not cross 1Mib boundaries.
This patch moves the space allocation and alignment ensurance
to of_get_fixed_tree and uses it in bootm. This is the first
step for making of_get_fixed_tree the single point of devicetree
handling in barebox.
of_get_fixed_tree now takes an argument of the input fdt. If it is
given, this one is used, otherwise an internal oftree is used which
will be created in subsequent patches.

There is no need to add the command name to the "usage" info when
defining a command.

We now have request_sdram_region to request a region. Use
it instead of a comparison with MALLOC_BASE.

whoever calls this function is not necessarily aware of a struct
image_data, so remove the dependency from the function.

Running the 'bootz' command always fails with
could not read <some file>
due to wrong usage of pointers and structures. This is the second try to fix
the 'bootz' command. At least on my target it is now be able again to load a
kernel without any error.

Running the 'bootz' command always fails with
could not read <some file>
due to it loads only a size of a pointer, instead of the size of the expected
header structure.

These images have to be located in the first 128MB of SDRAM, so
use the following strategy:
- first try to map the image. If the pointer is within the first
128MB of sdram everything is fine.
- if we can't map the image, check for SDRAM being smaller than
128MB we can use malloc for allocating space for the image.
- As a last fallback we simply put the image to 8MB into SDRAM.
This is not very clean. We try our best by checking that we
won't overwrite the malloc space.
