Status:
   The MCUXpresso SDK is released on a per-SoC basis, therefore we have a mix
   of versions:

   Some older Kinetis W family SoCs are not supported in MCUXpresso SDK, but
   instead are supported by the Kinetis Connectivity Software. This
   distribution is based on the same Kinetis SDK (ksdk) that MCUXpresso SDK
   evolved from. These older SoCs have many of the same peripherals as KW41Z,
   so we can reuse newer MCUXpresso SDK drivers from KW41Z, and import only the
   SoC header files from the Kinetis Connectivity Software.

   SoC		Version (Release Date)		Tag
   ----------------------------------------------------------------------------
   MCR20A	1.0.0				N/A
   MKW20Z4	1.0.1 (2015-12-10)		N/A
   MKW30Z4	1.0.1 (2015-12-10)		N/A
   MKW40Z4	1.0.1 (2015-12-10)		N/A

Purpose:
   Provides device header files and bare metal peripheral drivers for Kinetis,
   LPC, and i.MX SoCs. Zephyr shim drivers are built on top of these imported
   drivers to adapt the MCUXpresso SDK APIs to Zephyr APIs.

Description:
   This package is an extract from the upstream MCUXpresso SDK that contains
   only the files needed for Zephyr. Some directory structure changes are made
   to facilitate driver code reuse across multiple SoCs.

Dependencies:
   CMSIS header files

Patch List:

   * Changes from official delivery:
     - Fix ethernet timestamping driver. The nanosecond part of the frame
       timestamp wasn't saved.
     - Fix PTP event packet type check. The PTP message type was incorrectly
       checked.

   * Automatically enable ENET_ENHANCEDBUFFERDESCRIPTOR_MODE in HAL if gPTP
     support is enabled.
