0aa9e2ab change signature on x25519 mul because b[] length isnt always NLIMBS; thanks JMG for pointing out that this now causes a warning
7d7f6053 Change sub() so that it should work with non-propagate'd inputs. This has no effect on Strobe's usage of sub(), but it may reduce the risk of problems if the code is imported into other projects.

slightly so it won't warn..

The [5] change is the biggest question, and not sure how to
fix it better than this..

Need to think a bit more as it requires the test library, which isn't
immediately available...

Likely need to make this a proper package and put the library there..

One missing thing is the ability to generate public keys from
private keys for running the code standalone..

This also makes sure that the command works, and verifies that
a previous fix did fix things...

this also sets up for testing the public key version as well..

Slightly buggy in that it assumes all arrays are numbers though..

minor improvement to make sysinit_run a constructor, so don't need
to manually call it anymore...

This required updating the linker script for the l1 part to include
the linkerset section..

This is to help make sure everything you think is starting is..

This refactors out a bunch of code to make better use of the
SYSINIT mechanism...

Completes the PKI side of things for doing mutual authentication...

Uses a python script to generate the USB descriptors, and basic
interface code for the STM USB HAL Layer..  This gets ride of a lot
of the glue code that was previously written, allowing the glue code
to be easily changed/update...

break out the memory debug function into it's own file...

Minor fixes to the rs485 framing code...  Finally found the bug where
aborting a receive would corrupt the RX state for some reason...

Add back RNG seeding, and make it generic...

it's promoted to int (signed) which when shifting into the sign bit is
UB per §6.5.7 ¶ 4 of the C99 spec.

ST if free to contact me about licensing the code (or improving their
own code to be USB standard compliant)..

This follows the same protocol as the lora code, so the same
server should just work.

This gets USB CDC printing working..

add some more missing files now that it includes the symbols..
