<li>
<code>CONFIG_SPI_OWNBUS - Set if there is only one active device
on the SPI bus. No locking or SPI configuration will be performed.
It is not necessary for clients to lock, re-configure, etc..
</li>
<li>
<code>CONFIG_SPI_EXCHANGE</code>: Driver supports a single exchange method
(vs a recvblock() and sndblock ()methods)

<code>CONFIG_MMCSD_NSLOTS</code>: Number of MMC/SD slots supported by the driver. Default is one.

<h3>RiT P14201 OLED driver</h3>
<ul>
<li>
<code>CONFIG_LCD_P14201</code>: Enable P14201 support
</li>
<li>
<code>CONFIG_P14201_SPIMODE</code>: Controls the SPI mode
</li>
<li>
<code>CONFIG_P14201_FREQUENCY</code>: Define to use a different bus frequency
</li>
<li>
<code>CONFIG_P14201_NINTERFACES</code>:
Specifies the number of physical P14201 devices that will be supported.
</li>
<li>
<code>CONFIG_P14201_FRAMEBUFFER</code>:
If defined, accesses will be performed using an in-memory copy of the OLEDs GDDRAM.
This cost of this buffer is 128 * 96 / 2 = 6Kb.
If this is defined, then the driver will be fully functioned.
If not, then it will have the following limitations:
<ul>
<li>Reading graphics memory cannot be supported, and</li>
<li>All pixel writes must be aligned to byte boundaries.</li>
</ul>
</li>
</ul>
<h3>ENC28J60 Ethernet Driver Configuration Settings</h3>
<ul>
<li>
<code>CONFIG_NET_ENC28J60</code>: Enabled ENC28J60 support
