<h1>Intel&reg; x86 Coreboot/FSP Development Process</h1>
<p>
The x86 development process for coreboot is broken into the following components:
</p>
<ul>
<li>Coreboot <a target="_blank" href="SoC/soc.html">SoC</a> development</li>
<li>Coreboot <a target="_blank" href="Board/board.html">mainboard</a> development</li>
<li><a target="_blank" href="fsp1_1.html">FSP 1.1</a> integration</li>
</ul>
<p>
The development process has two main phases:
</p>
<ol>
<li>Minimal coreboot; This phase is single threaded</li>
<li>Adding coreboot features</li>
</ol>
<h2>Minimal Coreboot</h2>
<p>
The combined steps below describe how to bring up a minimal coreboot for a
system-on-a-chip (SoC) and a development board:
</p>
<table>
<tr bgcolor="#ffffc0">
<td>The initial coreboot steps are single threaded!
The initial minimal FSP development is also single threaded.
Progress can speed up by adding more developers after the minimal coreboot/FSP
implementation reaches the payload.
</td>
</tr>
</table>
<ol>
<li>Get the necessary tools:
<ul>
<li>Linux: Use your package manager to install m4 bison flex and the libcurses development
package.
<ul>
<li>Ubuntu or other Linux distribution that use apt, run:
<pre><code>sudo apt-get install m4 bison flex libncurses5-dev
</code></pre>
</li>
</ul>
</li>
</ul>
</li>
<li>Build the cross tools for i386:
<ul>
<li>Linux:
<pre><code>make crossgcc-i386</code></pre>
To use multiple processors for the toolchain build (which takes a long time), use:
<pre><code>make crossgcc-i386 CPUS=N</code></pre>
where N is the number of cores to use for the build.
</li>
</ul>
</li>
<li>Get something to build:
<ol type="A">
<li><a target="_blank" href="fsp1_1.html#RequiredFiles">FSP 1.1</a> required files</li>
<li><a target="_blank" href="SoC/soc.html#RequiredFiles">SoC</a> required files</li>
<li><a target="_blank" href="Board/board.html#RequiredFiles">Board</a> required files</li>
</ol>
</li>
<li>Get result to start <a target="_blank" href="SoC/soc.html#Descriptor">booting</a></li>
<li><a target="_blank" href="SoC/soc.html#EarlyDebug">Early Debug</a></li>
</ol>
