* remotes/kraxel/tags/ui-20190201-pull-request:
  ui: remove support for SDL1.2 in favour of SDL2
  hw/display/milkymist-tmu2: Move inlined code from header to source
  hw/display/milkymist-tmu2: Explicit the dependency to both X11 / OpenGL
  configure: LM32 Milkymist Texture Mapping Unit (tmu2) also depends of X11
  hw/display: Move Milkymist specific hardware out of common-obj list
