 existing virtio drivers with remote processor backends at a minimal development
 cost.
 
+The primary purpose of the remoteproc framework is to download firmware
+for remote processors and manage their lifecycle. The framework consists
+of several key components:
+
+- **Character Driver**: Provides userspace access to control the remote
+  processor.
+- **ELF Utility**: Offers functions for handling ELF files and managing
+  resources requested by the remote processor.
+- **Remoteproc Core**: Manages firmware downloads and recovery actions
+  in case of a remote processor crash.
+- **Coredump**: Provides facilities for coredumping and tracing from
+  the remote processor in the event of a crash.
+- **Userspace Interaction**: Uses sysfs and debugfs to manage the
+  lifecycle and status of the remote processor.
+- **Virtio Support**: Facilitates interaction with the virtio and
+  rpmsg bus.
