* Update to 2.0.0 SDK
* Board type needs to be set before earliest SDK setup
* Platform includes update
* Boot2 files
* Simple compilation issues
* Build and link
* PIO rebuild with version
* Newlib wrapper update
* Force inclusion of runtime_init_* fcns
The linker was dropping all references to the library's included
runtime_init_xxx functions and hence things like the IRQ vector
table and mutexes and alarms weren't properly set up leading to
instant crashes on start up..
Explicitly call out one function from the object file stored in
the .A to force the inclusion of all the functions. May be a better
way, heppy to hear any ideas.
