15c160301c scripts/get_default_envs.sh: preserve order of multiple entries for same variable
It's possible that the default_environment[] array contains multiple
entries for the same variable, e.g. a setting from env_default.h based
on some CONFIG_* variable, and another from
CONFIG_EXTRA_ENV_SETTINGS. In such a case, the last setting takes
effect.

Hence, in order to be able to use the output from this script as an
CONFIG_DEFAULT_ENV_FILE and get the same default environment as one
currently has, we need to preserve the order. So only sort by the
variable name, and disable the last-resort comparison.

We could pipe the result through uniq to remove duplicate lines, but I
think there's some value in seeing that certain variables are defined
multiple times.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

0778e7c50b script: Make the get_default_envs.sh script working with newest u-boot
This commit fixes several issues:

- After moving env related code to ./env directory the env_common.o file
is no longer present in the system (has been replaced with built-in.o).

- Use ${OBJCOPY} if available, fallback to system default's objcopy if not
present.

- Extend the script to accept different build directory than current one.
It is extremely handy with OE usage, where source code is separated from
build.

27229b2a4c scripts: Add script to extract default environment
This script looks for env_common.o object file and extracts from it default
u-boot environment, which is afterwards printed on standard output.

Usage example:
get_default_envs.sh > u-boot-env-default.txt

The generated text file can be used as input for mkenvimage.
