+   When we import libmetal we removed the tests/ and examples/ dir to reduce
+   the amount of code imported.
+
+Purpose:
+   HAL abstraction layer used by open-amp
+
+Description:
+   Libmetal provides common user APIs to access devices, handle device
+   interrupts and request memory across the following operating environments:
+
+   * Linux user space (based on UIO and VFIO support in the kernel)
+   * RTOS (with and without virtual memory)
+   * Bare-metal environments
+
+Dependencies:
+   Depends on Zephyr itself as it utilizes Zephyr's APIs to provide an
+   abstraction to open-amp.

+
+   When we import open-amp we removed the apps dir to reduce the amount of
+   code imported.
+
+Purpose:
+   IPC layer that implements rpmsg communication between cores.
+
+Description:
+
+This repository is the home for the Open Asymmetric Multi Processing (OpenAMP)
+framework project. The OpenAMP framework provides software components that
+enable development of software applications for Asymmetric Multiprocessing
+(AMP) systems. The framework provides the following key capabilities.
+
+* Provides Life Cycle Management, and Inter Processor Communication capabilities
+  for management of remote compute resources and their associated software
+  contexts.
+* Provides a stand alone library usable with RTOS and Baremetal software
+  environments
+* Compatibility with upstream Linux remoteproc and rpmsg components
+* Following AMP configurations supported:
+  a. Linux master/Generic(Baremetal) remote
+  b. Generic(Baremetal) master/Linux remote
+* Proxy infrastructure and supplied demos showcase ability of proxy on master
+  to handle printf, scanf, open, close, read, write calls from Bare metal
+  based remote contexts.
+
+Dependencies:
+   libmetal (https://github.com/OpenAMP/libmetal) - provides HAL layer
+   between OpenAMP and RTOS or OS environment.
