A VGA text mode driver. Supports a single 640x480, 80x60 color text mode with standard CGA color palette and font.
Generates image by indexing a VRAM for color and character data, pulling a bitmap from CGROM. Both memories use Xilinx's Block Memory Generator IP (v7.3).
Script scripts/cgrom_init.py generates the requisite COE file for the standard CGA font. scripts/vram_init.py generates a COE file for debugging the VRAM.
