+      instructions<Build-U-Boot-label>` for the updated steps.
+
+    - For Linux builds, generic ``defconfig`` is used instead of custom
+      fragments. Please refer to `linux users guide
+      <../../../linux/Foundational_Components_Kernel_Users_Guide.html#preparing-to-build>`__
+      for build instructions.
