* merged: nrf tree from unicore-mx
* fixed: small changes to make merged code play with rest of locm3 again
* added: linker script generator defines for nRF51/52 stubs
* added: doxygen support
This removes code and changes names and styles where relevant to be more
inline with normal libopencm3.
NRF52x library is built for hardfloat, M4F by default. The M4 no float
variants are less common, and if needed, the library can be built
manually for those variants. Unless some very common boards show up
using those parts, we don't need an extra library build.

Python2 is end-of-life [1] since the 1st of January 2020.
Some distributions (most notably: Debian and its derivatives) will stop
providing a `python` executable in order to encourage users to specify
the interpreter language of local scripts explicitly. Users of such
environments will be forced to work around this in one of these ways:
* create a virtual environment or
* manipulate the shebangs of the scripts or
* install the python2 package (as long as it is provided by distributions)
All currently maintained distribution releases provide python3.
In the near future distributions will need to remove python2, since it
is not maintained anymore.
PEP-394 [2] recommends to reference a specific python version
(python2 or python3), if the script is not expected to run in a virtual
environment.
Closes: #1265

* moved lpc43xx scripts to explicitly call python2, they have not been
ported, and are effectively unmaintained, but switching them to
python3 unconditionally would be unhelpful.
- Use libopencm3-template instead of libopencm3-examples as reference
on how to include libopencm3 to your project.
- Sourceforge website removed since it's only used for the mailing lists
which are listed immediately above.
- Small fixes
This has hurt many many many people over it's lifetime, by confusing their
multilib toolchains. Simply drop it outright. People who _really_ know what
they're doing are still perfectly entitled to "install" portions of this
project in suitable locations for their own use.
Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
Renamed every instance of variable CFLAGS in target specific Makefiles
to TGT_CFLAGS to free up CFLAGS for user defined compiler flags.
Added information in README.md about existence and usage of CFLAGS
environment variable in build process.
This converts all the YAML files to JSON files, as json parsing is built
into python instead of being a separate library requiring installation.
YAML is a superset of JSON, but putting comments in is not quite as obvious
as it is in yaml.
The following glue was used to convert yaml to json:
python -c 'import sys, yaml, json; json.dump(yaml.load(sys.stdin), sys.stdout, indent=4)' < $1 > $2
Clearly I haven't tested this on every single platform, and this
doesn't address the large blobs of yaml in the lpc4300 scripts directory,
only the cortex NVIC generation process.
I've tested a few IRQ driven example apps, and I've checked the generated
output of some known cases like the LM3s that has explicit gaps, and they are
all generated correctly.
We currently default to "-mfloat-abi=hard -mfpu=fpv4-sp-d16" for M4F cores, and
and variations of "-mfloat-abi=soft" for the others. Keep the M4F default, and
move others to no FP flags for consistency, but allow overriding these flags
via the FP_FLAGS environment variable.

Where the library is installed has quite an affect on what -L and -I
flags are used. If you install into the toolchain, you don't want
to use them at all, but if you install out of tree (/opt/mycm3 for
example) you need to specify the -L and -I flags.
Update the documentation and the example makefiles to support this
