Version:
   v5.6.1

Purpose:
   Add support for Silicon Labs EXX32 SoCs

Description:
   This code component is used to add Zephyr support for Silicon Labs EXX32 SoCs.
   To speed up the development process it is based on the Silicon Labs HAL.

   The Silicon Labs HAL is split into SoC specific folders. They share the 
   Peripheral Support library.

   The following folders are imported:
   platform/Device/SiliconLabs/$(GECKO_DEVICE)
   platform/emlib

Dependencies:
   This source code depends on headers and sources from Zephyr:
   ext/hal/cmsis

How to update
+++++++++++++

  * Start Simplicity Studio
  * Start the Package Manager
  * Install the 32-bit MCU SDK with the version you want to update to
  * The installation directory is <Simplicity Studio Path>/developer/sdks/gecko_sdk_suite/<version>
  * Replace the necessary files in ext/hal/silabs/gecko/Device and ext/hal/silabs/gecko/emlib
  * Ensure that the CMakeLists and Kconfig files match the new version of the Gecko SDK

The following folders are used in this HAL:
