At present U-Boot environment variables, and thus scripts, are defined
by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text
to this file and dealing with quoting and newlines is harder than it
should be. It would be better if we could just type the script into a
text file and have it included by U-Boot.
Add a feature that brings in a .env file associated with the board
config, if present. To use it, create a file in a board/<vendor>
directory, typically called <board>.env and controlled by the
CONFIG_ENV_SOURCE_FILE option.
The environment variables should be of the form "var=value". Values can
extend to multiple lines. See the README under 'Environment Variables:'
for more information and an example.
In many cases environment variables need access to the U-Boot CONFIG
variables to select different options. Enable this so that the environment
scripts can be as useful as the ones currently in the board config files.
This uses the C preprocessor, means that comments can be included in the
environment using /* ... */
Also support += to allow variables to be appended to. This is needed when
using the preprocessor.

WIth EFI we must embed the devicetree in an ELF image so that it is loaded
as part of the executable file. We want it to include the binman
definition in there also, which in some cases cannot be created until the
ELF (u-boot) is built. Add an option to binman to support writing the
updated dtb to the ELF file u-boot.out
This is useful with the EFI app, which is always packaged as an ELF file.

Since commit e57c7c5c42 ("get_maintainer.pl: update from Linux kernel
v5.13-rc6") only the top level MAINTAINERS file is used. This is because
this commit (accidentally) disabled the search of MAINTAINERS files
(find_maintainer_files is set to 0 again). Before that, commit
b79372ae94 ("scripts/get_maintainer.pl: enable find_maintainer_files")
explicitly enabled that feature. Nowadays, we also have to set
maintainer_path to a directory.
To fix it and enable recursive search of MAINTAINERS, create a
configuration file to set these two variables.
