<p>The Minnowboard is an Atom-based x86 board (Intel E38xx
Series SoC) in a maker-friendly form-factor: it provides
convenient access to pins that can be used to connect
peripherals using one of the standard buses: GPIO, SPI, or I2C.
These buses are more common in the ARM/MIPS world than in x86,
so while &os; was able to boot just fine, it lacked support for
these buses on the MinnowBoard.</p>
<p>As of r310645, HEAD support all three buses via
<tt>ig4(4)</tt>, <tt>bytgpio(4)</tt>, and <tt>intelspi</tt>
drivers. The <tt>ig4(4)</tt> and <tt>bytgpio(4)</tt> changes
were backported to 11-STABLE; <tt>intelspi</tt> will be MFCed in
couple of weeks.</p>
