title: Yocto: Is there a way to remove items of SRC_URI in local.conf?
body: <p>We are using custom kernel, so I override variables defined in linux-imx_xxx.bb:</p>
  
  <pre><code>KERNEL_SRC_pn-linux-imx = "our_url"
  SRCBRANCH_pn-linux-imx = "our_branch"
  SRCREV_pn-linux-imx = "${AUTOREV}"
  </code></pre>
  
  <p>It works. But many patch files added in linux-imx_xxx.bb and out custom kernel have patched. </p>
  
  <p>So I want to just remove patch files in local.conf, and not touch any .bb files defined in official meta-fsl-* layers. </p>
  
  <pre><code>SRC_URI_remove_pn-linux-imx = " file://*.patch"
  </code></pre>
  
  <p>But this doesn't work. So is there a way to do this in local.conf?</p>
  
  <p>BTW I know the .bbappend should works, but again, I don't want change any meta-fsl-* layers.</p>
