Subject: powerpc/85xx: p2020: Move all P2020 DS machine descriptions to
 p2020.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This moves P2020 DS machine descriptions into new p2020.c source file.
This is preparation for code de-duplication and providing one unified
machine description for all P2020 boards.
