NOMERGE (work-in-progress)

Read display EDID when bootloader starts, to determine attached screen resolution. At the moment we only detect 720x720 (bundled Tiliqua screen), and if this is not available, switch to 1280x720 (supported by most monitors).

Changes:

  • Add SoC peripheral to allow CPU to dynamically configure video timings used by the DVI serializer
  • Add tiny EDID parser used by the bootloader to determine attached display capabilities
  • Modify draw libraries to take dynamic h/v width so we can dynamically scale
