Description

A display board using a tiny FPGA to allow simple use of a 320x240 display.

The board currently has the following known issues:

The beeper capacitor should be replaced with a 68ohm resistor
The HyperRAM part is not connected to DDR capable IO within the Trion FPGA, making it incompatible with Efinix's provided IP core. To use it a custom PHY will need writing (and it will never reach as high bandwidth).
The JTAG programming header is missing the CRESET_N and SS_N pins, these need to be added to improve debugging cabability
The FPGA will not currently configure itself from Flash - still investigating this issue...

Otherwise, everything else is working fine!
