+
+The ``ADSP_ROOT`` environment variable specifies a default value
+for the :variable:`CMAKE_ADSP_ROOT` variable when there is no explicit
+configuration given on the first run while creating a new build tree.

+Cross Compiling for ADSP SHARC/Blackfin
+---------------------------------------
+
+Cross-compiling for ADSP SHARC or Blackfin can be configured
+by setting the :variable:`CMAKE_SYSTEM_NAME` variable to ``ADSP``
+and the :variable:`CMAKE_SYSTEM_PROCESSOR` variable
+to the "part number", excluding the ``ADSP-`` prefix,
+for example, ``21594``, ``SC589``, etc.
+This value is case insensitive.
+
+CMake will automatically search for CCES or VDSP++ installs
+in their default install locations
+and select the most recent version found.
+CCES will be selected over VDSP++ if both are installed.
+Custom install paths can be set via the :variable:`CMAKE_ADSP_ROOT` variable
+or the :envvar:`ADSP_ROOT` environment variable.
+
+The compiler (``cc21k`` vs. ``ccblkfn``) is selected automatically
+based on the :variable:`CMAKE_SYSTEM_PROCESSOR` value provided.

+---------------------------
+
+* The ADSP compiler (SHARC and Blackfin) now supports
+  both CCES and VDSP++ installations,
+  with required configuration now done in the compiler module itself
+  rather than the Generic-ADSP platform module.
+
+* A dedicated ``ADSP`` platform has been added
+  to replace the existing ``Generic-ADSP`` implementation.
+  This features automatic detection of the latest CCES/VDSP++ install
+  and compiler selection (``cc21k`` vs. ``ccblkfn``)
+  based off of the :variable:`CMAKE_SYSTEM_PROCESSOR` variable.

+When :ref:`Cross Compiling for ADSP SHARC/Blackfin`,
+this variable holds the absolute path to the latest CCES or VDSP++ install.
+The directory is expected to contain the ``cc21k.exe`` and ``ccblkfn.exe`` compilers.
+This will be set automatically if a default install of CCES or VDSP++ can be found.
+
+See also the :envvar:`ADSP_ROOT` environment variable.
