[PATCH] pm2fb: Manual configuration of timings for Elsa Winner 2000 Office
Attached is a small patch which configures the correct memory clock and
timings on the Elsa Winner 2000 Office pm2 based card. This is necessary when
the card is used on a platform which does not support PC style BIOS
initialization.
