Run tools/nxsthyle against all files and eliminate as many complaints as is reasonable.
Run tools/rmcr to eliminate all dangling garbage at the end of lines.
Run tools/detab to eliminate all TAB characters from the files.

configs/omnibusf4: Initial support for the OmnibusF4 family of flight
management units.
"OmnibusF4" is not a product name per se, but rather a design spec
that many product vendors adhere to. The spec defines the major
components, and how those components are wired into the
microcontroller.
Airbot is one such vendor, and they publish a schematic here:
http://bit.ly/obf4pro
Other software that supports the OmnibusF4 family include Betaflight,
iNAV, and many others. PX4 recently added support as well, using their
own, non-upstreamed, bespoke port of NuttX. No code from those
resources is included in this port.

/* These 'addresses' of these values are setup by the linker script. They

|
|
*
|
|
* - The linker script defines, for example, the symbol_sdata.

|
|

|
