Building of final u-boot.bin binary for mpc85xx via binman is needed only
when inserting DTB binary in the middle of the u-boot ELF binary (before
.bootpg and .resetvec ELF sections).
These requirements are met when CONFIG_MPC85XX_HAVE_RESET_VECTOR is enabled
(= generating .bootpg/.resetvec sections) and CONFIG_OF_SEPARATE is enabled
(= inserting DTB binary).
So in all other cases use standard build procedure instead of custom
mpc85xx u-boot.bin Makefile target via binman.

Currently Makefile produces final mpc85xx image when SPL is not used in
custom file u-boot-with-dtb.bin. It is quite confusing name as build
process produce also intermediate file standard file u-boot-dtb.bin (which
is just intermediate and not bootable). Other platforms use u-boot.bin
(UBOOT_BIN) as standard name for final bootable raw image.
So change Makefile rules and binman to produce final bootable file for
mpc85xx also into file u-boot.bin. There is just need for mpc85xx to not
define default rule for u-boot.bin then instruct binman (via DTS file) to
store final image into u-boot.bin (instead of u-boot-with-dtb.bin) and
finally rename target u-boot-with-dtb.bin to u-boot.bin.
With this change are also removed custom Makefile hacks for mpc85xx that it
produced non-standard output file. And also updated documentation.

Running tests in parallel is much faster, e.g. 15 seconds to run the tests
on sandbox (only), instead of 100 seconds (on a 16-core machine). Add a
'make pcheck' option to access this feature.
Note that the tools/ tests still run each tool's tests once after the
other, although within that, they do run in parallel. So for example,
the buildman tests run in parallel, then the binman tests run in
parallel. There would be a signiificant advantage to running them all
in parallel together, but that would require a large amount of
refactoring, e.g. with more use of pytest fixtures.

This is done on the one hand for a better overview and

hand it is to synchronize the output with the script
get_default_env.sh, which generated a sorted default

should be. It would be better if we could just type the script into a

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 /* ... */

According to Nick Desaulniers:
"This is a known difference between GNU and LLVM linkers; the GNU
linkers permit relocations in readonly segments (making them not read
only), LLVM does not (by default)."
Since U-Boot apparently seems to use relocations in readonly segments,
change the global linker flags to permit them when linking with LLD by
specifying '-z notext'.
