/* ENC28J60 Configuration Settings:

* CONFIG_NET_ENC28J60 - Enabled ENC28J60 support
* CONFIG_ENC28J60_OWNBUS - Set if the ENC28J60 is the only active device on
* the SPI bus. No locking or SPI configuration will be performed. All
* transfers will be performed from the ENC2J60 interrupt handler.
* CONFIG_ENC28J60_SPIMODE - Controls the SPI mode
* CONFIG_ENC28J60_FREQUENCY - Define to use a different bus frequency
* CONFIG_ENC28J60_NINTERFACES - Specifies the number of physical ENC28J60

* will be supported.
* CONFIG_P14201_FRAMEBUFFER - 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:
*
* - Reading graphics memory cannot be supported, and
* - All pixel writes must be aligned to byte boundaries.
*
* Required LCD driver settings:
* CONFIG_LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will be accepted.
