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"

This optionally enabled the MMU in the PBL or during early startup for

MMU later. This might complicate debugging early code, so this has been

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.

This has several improvements for the oftree command:
- loading a devicetree (-l) and actually probing (-p) it now is separated
- the command now can dump the internal devicetree or a dtb given on the
command line.
- The -f option now actually frees the internal devicetree
With this the usage pattern for this command is:
oftree -l /env/oftree
oftree -d -n /sound
oftree -d /env/oftree
oftree -f
oftree -p
oftree -l -p /env/oftree

Fix size address calculation.
Global variables from <asm/sections.h> which are defined
in linker script *.lds files for end addresses has already
a +1 calculation.
For example:
stext = 0x100 with a size about 0x50 will result a etext = 0x150.
In this case a correct size calculation is (etext - stext) = 0x50.
In function 'request_sdram_region' the end address will be
calculated with (start + size - 1) which result a correct
end address of 0x149 in this example.
