In theory we can overwrite a builtin command with a script. However,
I don't know a single case where this has been done. Scripts are
often more unflexible than commands so it's unlikely that a script
can extend the functionality of a builtin command. Moreover, the
internal command is no longer accessible once it's overwritten by
a script.
Invert this logic so that a builtin command can overwrite an existing
script. This will help when the 'boot' script is converted to a
builting command. Then with old environments the builtin command will
be used instead of the script.

The bootm code is now independent from the actual bootm command, so
compile the ARM specific bootm code based on CONFIG_BOOTM and not on
CONFIG_CMD_BOOTM.

We used to use struct image_data as the central data structure for bootm and
also as the input data structure. This makes it unclear which of the fields
are actually input data. This patch creates a struct bootm_data which is
exclusively used for input data to make usage clearer.
Also it moves the dispatching of multifile uImage pathnames to the core bootm
code so that the core code gets more flexible and the command code simpler.

The Altera SoCFPGAs expect a simple header for their first stage
loaders. This adds a tool to generate images for the SoCFPGAs. The
header is either embedded into the image or optionally prepended
to the image. In this case code is added to jump over the image
header.

The data caches should be invalided once during startup. This should
also be done when we do not have the MMU enabled in barebox because
the Kernel does not invalidate the caches during start.
To make this sure this patch enables the arm_early_mmu_cache_invalidate
function even if MMU support is disabled. Additionally this patch adds
calls to arm_early_mmu_cache_invalidate in start.c and uncompress.c.

Some of the irq can still be on after a reset or power on as the IP are
powered by the backup power. This could lead to an interrupt dead lock
when the kernel boot. So disable them before booting.
