The hexiwear board pairs two Kinetis SoCs - k64 and kw40. The k64
already has SoC support in Zephyr, therefore we are adding support for
another board for the same SoC. Note, however, that hexiwear uses a
different SoC package than the Freedom board and therefore has a
different part number and pinout.
The second SoC on the hexiwear board, kw40, runs a BLE controller stack
with HCI; it does not run Zephyr (yet).
