Status:
   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)
   ----------------------------------------------------------------------------
   MCR20A	1.0.0
   MKW20Z4	1.0.1 (2015-12-10)
   MKW30Z4	1.0.1 (2015-12-10)
   MKW40Z4	1.0.1 (2015-12-10)

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 cloned from the Github for mcux-sdk. The cloned package is then copied and committ'ed
    into NXP's Zephyr HAL. Care should be taken to retain local changes to the SDK files that are documented
    in Patch List section of the document.

Dependencies:
   CMSIS header files

Patch List:
  1. Delete the .a binary archive files after an SDK update before committing the changes. These files are still present in the SDK github repo but have been
     deleted from the Zephyr HAL
  2. mcux-sdk/drivers/caam/fsl_caam.c: Move used job descriptors in the CAAM driver from the stack to noncacheable section. At time of writing, there should
     be four being used for entropy in zephyr.
  3. fsl_common.h: add #ifdef ZEPHYR #endif to include Zephyr's sys utils
  4. mcux-sdk/drivers/pit/fsl_pit.c: add guards to avoid compilation warnings when building
     with SDK clock control driver disabled.
  5. devices: MIMX8QM6: Add header files for QM's DSP core
  6. devices: MIMX8QM6_dsp.h: Adjust DSP core interrupts
  7. devices: MIMX8QM6_dsp.h: Add missing LPUART IRQ macro
  8. MIMX8QM6: drivers: fsl_clock.c: Report NULL frequency for unsupported core
  9. devices: MIMX8QX6: Add header files for QXP's DSP core
  10. MIMX8QX6: scfw_api: Switch to including generic fsl_device_registers.h
  11. mcux-sdk/drivers/i3c/fsl_i3c.c: add guards to avoid compilation warnings when building
      with SDK clock control driver disabled for SoC has no reset driver.
  12. MCUXGH-1081[IRQSTEER] Improve for portability
  13. drivers: irqsteer: Add function for querying the master interrupts status
  14. devices: MIMX8ML8: Fix naming inconsistency
  15. devices: MIMX8ML8: Add missing FSL_FEATURE_* macros
  16. devices: MIMX8ML8: fsl_clock: Add missing definitions for IRQ_STEER
  17. devices: MIMX9352: Add new SAI-related FSL_FEATURE_* macros
  18. drivers: fsl_sai: Allow enabling/disabling implicit channel configuration
  19. drivers: fsl_sai: Allow NULL FIFO watermark
  20. drivers: fsl_sai: Fix compilation warnings when asserts are disabled
  21. mcux-sdk/drivers/ftm/fsl_ftm.c: make public FTM_GetInstance() function (mcux-sdk#155)
  22. mcux-sdk-middleware-usb: fix ip control return value for ip3511
  23. drivers: edma: Introduce revision 2 of eDMA driver
  24. devices: MIMX9352: Add SoC layer definitions required for using edma rev2
  25. exclude the following directories and files from mcux-sdk update to reduce HAL size:
     - mcux-sdk\manifests
     - mcux-sdk\middleware\issdk\docs
     - mcux-sdk\docs
  26. mcux: mcux-sdk: Fix "loop" labels in inline assembly to use unique identifiers.
  27. mcux-sdk-middleware-usb: Fix build issues with the code from github
