Documentation: boards: stm32mp: document environment partition ...

We have barebox get its environment out of a "barebox-environment"
partition. The BootROM and first stage bootloader both select partitions
on name not UUID, so we're following suit.

Documentation: make gen_commands helper python3 compatible ...

On some machines the python command is provided by Python 3 while on
most (at least in my bubble) it is still Python 2. Modify the code to
make it usable by both Python versions.

print_function is available in __future__ since Python 2.6.0a2, which
shouldn't be a relevant restriction.

The modified script generates the same documentation as the old one;
independent if the script is called using Python 2 (here: 2.7.16) or
Python 3 (here: 3.7.3).

blspec: add support for devicetree overlays ...

Read the devicetree-overlay property from the blspec entry and register
the overlays when booting the blspec entry.

Do not fail the boot if an overlay cannot be loaded, because if Linux
fails to boot without an overlay, the base device tree is broken.

Documentation: zii-imx7d-dev: Fix errors with openocd configuration script ...

When attempting to use the existing configuration file to bootstrap an
RMU2 board, openocd would consistently fail in the 'safe_reset' function
with a number of errors.

Disabling the internal reset handling (similar to what's done on the
i.MX7 Sabre boards) allowed barebox to download and run successfully.

Tested with openocd-0.10.0+dev-00924-g16496488 on a Zodiac RMU2.

Documentation: zii-vf610-dev: Fix 'halt' in openocd configuration script ...

When attempting to use the existing configuration file to bootstrap
an SCU4 AIB board, openocd would consistently fail on the 'halt' command
with a "Target not examined yet" error.  Dumping target information
showed that vf610.cpu1 was the active target, rather that vf610.cpu0.

Adding a command prior to the halt to explicitly set the target core
resulted in proper operation.

Tested with openocd-0.10.0+dev-00924-g16496488 on a Zodiac SCU4 AIB.
