RGB2RTG is licensed under the GNU General Public License, version 2 only
(GPL-2.0-only). The full text is in COPYING.

Rationale: the chipset core contains code from UAE and WinUAE (GPL; Bernd
Schmidt, Alessandro Bissacco, Toni Wilen and others), much of it the older UAE
code kept in E-UAE - see package/UAE-WinUAE-notice.txt and each file's header.
The kernel combines it with Emu68 (MPL-2.0, Michal Schulz): MPL-2.0 section 3.3
allows that combination under the GPL, and Emu68's own files keep their MPL-2.0
notices.

Under the MPL-2.0 instead (full text in MPL-2.0.txt):
  kernel/emu68-rgb2rtg.patch  our changes to Emu68's files - MPL-2.0, like the
                              files they change
  driver/VideoCore.card/      the RTG driver: Emu68-tools' VideoCore.card with
                              our changes (each file's header says so)
