Porting status

Tasks:

• Build system config
  • Cortex-M4 core
  • Cortex-M0+ core
  • RI5CY core
  • ZERO-RISCY core
• linker scripts
  • CM4 memory region
  • CM0+ memory region
• flashing (openocd support?)
• boot single core
• gdb connection
• reusing kinetis periph drivers
• UART stdio
• new/unsupported modules:
  • SCG (clocking)
  • PCC (module clocks)
  • LPI2C
  • LPSPI
  • LPIT
  • TRNG (also found in kw41z)
  • SEMA42
  • MU
  • MMDVSQ
• Radio driver porting (kw41zrf should work with small changes drivers: Add support for KW41Z builtin transceiver #7107)
• multi core operation TBD
  • linking multi core binary for flashing

And of course, I hope for an integration into RIOT, since I see a huge potential for RISC-V in the future :)
