startup: Add initcall tracing debug option ...

Being able to trace initcall is very useful when trying to
find out where startup hangs. This adds a kconfig option for
it to make it easier to access.

remove unused debug Kconfig options ...

ENABLE_DEVICE_NOISE is used only in two network drivers and is
otherwise unused. ENABLE_FLASH_NOISE is completely unused.
ENABLE_PARTITION_NOISE enables DEBUG in the partition command,
but this code has no debug messages at all.

Remove all this.

ARM: Add relocatable binary support ...

For making the same binary executable on different SoCs which have
different DRAM addresses we have to be independent of the compile
time link address.

This patch adds relocatable binary support for the ARM architecture.
With this two new functions are available. relocate_to_current_adr
will fixup the binary to continue executing from the current position.
relocate_to_adr will copy the binary to a given address, fixup the
binary and continue executing from there.

For the PBL and the real image relocatable support can be enabled
independently. This is done to (hopefully) better cope with setups
where the PBL runs from SRAM or ROM and the real binary does not.

defaultenv-2: add boot sequence ...

This allows to boot a sequence of boot entries until one succeeds.

boot sources can be passed in $global.boot.default, which is now treated
as a list. Also a list of boot entries can be specified as arguments
to the boot script. The entries can be:

- a plain filename from /env/boot/
- a full path to an arbitrary file
- a directory containing boot entries

With this this command:

boot net nand-ubi /env/boot.d

would first use the /env/boot/net entry, if this fails the /env/boot/nand-ubi
entry and if this also fails the files from /env/boot.d/ (which could also
be links to boot scripts)

To make the above the default, global.boot.default would be specified as:

global.boot.default="net nand-ubi /env/boot.d"

ARM: Enable mmu early ...

This optionally enabled the MMU in the PBL or during early startup for
the non PBL case. The regular MMU init code will pickup the already enabled
MMU later. This might complicate debugging early code, so this has been
made optional.

startup: call a barebox_main function pointer at the end of the startup ...

Currently Kconfig dependencies are used to allow non-interactive builds.
This leads to problems in Kconfig getting the dependencies right.

This patch adds a barebox_main function pointer which is called at the
end of the startup process. This defaults to run_shell when a shell is
enabled.

With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive
builds can now be enabled for every board allowing to compile a binary
without further Kconfig dependencies. This also allows for more flexibility,
for example boards may decide to try non-interactive startup first and
call run_shell if that fails.

Add in-system barebox update infrastructure ...

Currently in-system update means to write an arbitrary file to
an arbitrary device. There is no sanity check if the flashed image
is of the right type or will fit onto the device. Furthermore some
SoCs need a special preparation step for their images before
flashing them.

This adds a barebox in-system update infrastructure. Boards can
register update handlers which know how to make the board bootable.
The available handlers can be listed to be able to select one,
different force levels give the user the chance to know it better.
