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.
Wrong since original commit in 2013.
LCD code can't actually automatically determine clock speed if it's HSE,
as we don't know here whether what HSE is, nor what it's divided by.
For more fun, that old 2014 API doesn't have any way of flagging that it
failed either. Hooray.
We did have
* _HPRE_SYSCLK_DIVN (3 parts)
* _HPRE_DIVN (5 parts)
* _HPRE_DIV_N (4 parts)
Unify all on _HPRE_DIVN. Provide deprecated definitions to not break
everything at once.
Also, standardize on "NODIV" instead of DIVNONE.
We already had the hooks for ccmram and ram1 and ram2 and ram3 and xsram
for "other" ram sections, but there was no method, out of the box, for
placing a function in "normal" ram. The "easy" method of labelling a
function as ".data.someramfunc" causes warnings because code isn't meant
to have a name like ".data*" so we must explicitly add a new code
section.

Add support for a section(s) ".noinit*" that will be allocated in ram,
but not cleared or initialized. This can be used for passing variables
between a bootloader and an app for instance, or even just between
restarts of your application.
Without any assigned usages of the section, there is zero change in ram
usage. The align does nothing when the prior section was already
aligned.
These defines were simply a word containing the number, instead of the
number itself. This provides no value, and implies that there's a
limited set of values. The list was _already_ incomplete, so
misleading, _and_ just noise to maintain. Burn it all.
(well, burn it just a little bit, provide deprecated aliases on the old
values so that code keeps compiling)
We were never going to be capable of supporting every single part
variant with their own files, so stop trying. We've been supporting the
linker script generator for a long time now, so move on from these old
static files.
Breaking: if you were using one of these, and don't wish to use the
linker script generator, you should simply declare a stub linker script,
and include the generic section definitions file, and provide this in
your own application.
Old:
LDSCRIPT = $(OPENCM3_DIR)/lib/stm32/l1/stm32l15xxb.ld
New (linker script generator):
DEVICE=stm32l151cb
New (manual):
* Add file mymemorymap.ld, with contents similar too:
```
MEMORY
{
rom (rx) : ORIGIN = 0x08000000, LENGTH = 256K
ram (rwx) : ORIGIN = 0x20000000, LENGTH = 48K
}
/* Include the common ld script. */
INCLUDE cortex-m-generic.ld
```
LDSCRIPT=mymemorymap.ld
See ld/README for more information on using the linker script generator
Replaced & with &&
Wait for all three bits to be set - SB, MSL, and BUSY.
Old code worked by chance, use booleans to correctly convey intent.

- 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
V=s is openwrt, V=1 is here.
try and avoid weird problems with missing files like,
make[1]: *** No rule to make target '../../../include/libopencm3/stm32/g4/pwr.h', needed by 'rcc_common_all.o'. Stop.
by turning down the paralellism a bit, it's a quad core arm, but it's
stil a little small machine.
