This renames the dcdofs config option in the imx-image tool to ivtofs. dcdofs
is a misnomer. The DCD (Device Configuration Data) is only one part of the data
linked into the IVT (Image Vector Table), but the meaning of the option is
really the latter, not the former.

This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.
The advantage is that these specifiers are machine-parseable which helps
license conformance, e.g. for packaging barebox in Debian.
While touching these files also do some minor comment reformatting to
get some uniform layout.

Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.

barebox_arm_reset_vector() is a global function but we never provided a
prototype anywhere. The prototypes differ for the different boards, so
to provide a common prototype we must harmonize them.
void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2)
Should be suitable for all boards.

Currently it's hardcoded for each board which defaultenv version is
used. This is unfortunate since some people like the other defaultenv
version better and may want to select it.
This patch removes the board specific environment path
CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via:
if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC))
defaultenv_append_directory(defaultenv_<board>);
This way we can make sure that the defaultenv-1 board specific bits are
only compiled in when defaultenv-1 is actually in use.
The next step is to make the defaultenv version selection a user visible
choice.

The imx53 SOC features 128kB of internal SRAM which is commonly used in
early stages of barebox to store the stack. Avoid magic numbers while
addressing this RAM.

This file originates in Linux. Linux has it under include/linux/

Let's move it to the same place as well in barebox.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.
Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

With compressed image support TEXT_BASE will become the base
address of the uncompressed image. What the boards want instead
is the base address of the decompressor code or, if not compressed,
the base address of the uncompressed image. Use _text which is
the correct one for both cases.

us to change pad settings using logic operations. Also with this we

Traditionally U-Boot and barebox have the exception vectors at
the start of the binary. There is no real reason in doing so,
because in the majority of cases this data will not be at 0x0
where it could be used as vectors directly anyway.
This patch puts the vectors into a separate linker section and
defines an head function which is placed at the start of the
image instead. Putting this in a separate function also has
the advantage that it can be placed at the start of images
which require an additional header like several Freescale i.MX
images. As the head function contains the barebox arm magic
those images can now also be detected as barebox images.
