fbdev: platforming hecubafb and n411

- This enables support for the Hecuba board. This driver was tested
- with an E-Ink 800x600 display and x86 SBCs through a 16 bit GPIO
- interface (8 bit data, 4 bit control). If you anticipate using
- this driver, say Y or M; otherwise say N. You must specify the
- GPIO IO address to be used for setting control and data.
+ This enables support for the Apollo display controller in its
+ Hecuba form using the n411 devkit.

- * The interface between Hecuba and the host is TTL based GPIO. The
- * GPIO requirements are 8 writable data lines and 6 lines for control.
- * Only 4 of the controls are actually used here but 6 for future use.

*
- * General notes:
- * - User must set hecubafb_enable=1 to enable it
- * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR
+ * It is intended to be architecture independent. A board specific driver
+ * must be used to perform all the physical IO interactions. An example
