+Kexec Handover Concepts
+=======================
+
+Kexec HandOver (KHO) is a mechanism that allows Linux to preserve state -
+arbitrary properties as well as memory locations - across kexec.
+
+It introduces multiple concepts:
+
+KHO Device Tree
+---------------
+
+Every KHO kexec carries a KHO specific flattened device tree blob that
+describes the state of the system. Device drivers can register to KHO to
+serialize their state before kexec. After KHO, device drivers can read
+the device tree and extract previous state.
+
+KHO only uses the fdt container format and libfdt library, but does not
+adhere to the same property semantics that normal device trees do: Properties
+are passed in native endianness and standardized properties like ``regs`` and
+``ranges`` do not exist, hence there are no ``#...-cells`` properties.
+
+KHO introduces a new concept to its device tree: ``mem`` properties. A
+``mem`` property can inside any subnode in the device tree. When present,

+Kexec Handover Usage
+====================
+
+Kexec HandOver (KHO) is a mechanism that allows Linux to preserve state -
+arbitrary properties as well as memory locations - across kexec.
+
+This document expects that you are familiar with the base KHO
+:ref:`Documentation/kho/concepts.rst <concepts>`. If you have not read
+them yet, please do so now.
+
+Prerequisites
+-------------
+
+KHO is available when the ``CONFIG_KEXEC_KHO`` config option is set to y
+at compile team. Every KHO producer has its own config option that you
