 Toolchains
 **********
 
-The MT8195 toolchain is already part of the Zephyr SDK, so builds for
-the ``mt8195//adsp`` board should work out of the box simply following
-the generic Zephyr build instructions in the Getting Started guide.
-
-The MT8186 toolchain is not, and given the proliferation of Xtensa
-toolchains in the SDK may not be.  The overlay files for the device
-are maintained by the SOF project, however, and building a toolchain
-yourself using crosstools-ng is not difficult or time-consuming.  This
-script should work for most users:
-
-.. code-block:: shell
-
-   #!/bin/sh
-
-   TC=mtk_mt818x_adsp
-
-   # Grab source (these are small)
-   git clone https://github.com/crosstool-ng/crosstool-ng
-   git clone https://github.com/thesofproject/xtensa-overlay
-
-   # Build ct-ng itself
-   cd crosstool-ng
-   ./bootstrap
-   ./configure --enable-local
-   make -j$(nproc)
-
-   mkdir overlays
-   (cd overlays; ln -s ../../xtensa-overlay/xtensa_mt8186.tar.gz xtensa_${TC}.tar.gz)
-
-   # Construct a .config file
-   cat >.config <<EOF
-   CT_CONFIG_VERSION="3"
-   CT_EXPERIMENTAL=y
-   CT_OVERLAY_LOCATION="overlays"
-   CT_OVERLAY_NAME="${TC}"
-   CT_ARCH_XTENSA=y
-   CT_XTENSA_CUSTOM=y
-   CT_TARGET_VENDOR="${TC}_zephyr"
-   CT_TARGET_CFLAGS="-ftls-model=local-exec"
-   CT_CC_GCC_CONFIG_TLS=n
-   CT_GDB_CROSS_EXTRA_CONFIG_ARRAY="--enable-xtensa-use-target-regnum --disable-xtensa-remote-g-packet"
-   EOF
-
-   # Build
-   ./ct-ng olddefconfig
-   ./ct-ng build.$(nproc)
-
-After this completes, you will find your toolchain in ``~/x-tools``
-and can use it to build by setting it as your Zephyr cross compiler:
-
-.. code-block:: shell
-
-   export CROSS_COMPILE=$HOME/x-tools/xtensa-mtk_mt818x_adsp_zephyr-elf/bin/xtensa-mtk_mt818x_adsp_zephyr-elf-
-   export ZEPHYR_TOOLCHAIN_VARIANT=cross-compile
+The MT8195, MT818X and MT8365 toolchains are already part of the Zephyr
+SDK, so builds for the ``mt8195/mt8195/adsp``, ``mt8186/mt8186/adsp``,
+``mt8188/mt8188/adsp`` and ``mt8365/mt8365/adsp`` board should work out
+of the box simply following the generic Zephyr build instructions in
+the Getting Started guide.
