title: How to create a defconfig file from a .config?
body: <p>I have done <code>make menuconfig</code> for a board <code>defconfig</code> and modified few configurations. When I select save, a new <code>.config</code> was created in the Kernel top directory.</p>
  
  <p>I want to create new <code>defconfig</code> for this <code>.config</code> file created.</p>
  
  <p>Can I copy the <code>.config</code> as a new <code>defconfig</code> and copy to <code>arch/arm/configs/</code>?</p>
  
  <pre><code>$ cp .config arch/arm/configs/board_new_defconfig
  </code></pre>
