+  Add the FSP binary to the coreboot flash image using the following command:
+</p>
+<pre><code>util/cbfstool/cbfstool build/coreboot.rom add -t fsp -n fsp.bin -b &lt;base address&gt; -f fsp.bin</code></pre>
+<p>
+  This command relocates the FSP binary to the 4K byte aligned location in CBFS so that the
+  FSP code for TempRamInit may be executed in place.
