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
will be fully functional. 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.
The latter limitation effectively reduces the 128x96 disply to 64x96.

CONFIG_NET_ENC28J60 - Enabled ENC28J60 support
