[U-Boot-Users] [PATCH 3/5] 4xx: Update APC405 board support
Matthias Fuchs
matthias.fuchs at esd-electronics.com
Mon Apr 21 14:42:11 CEST 2008
- enable esd's auto_update mechanism
- fix LCD support on latest hardware revision (uses other LCD controller)
- support alternative flash layout on rev. 1.8 boards
- coding style cleanup
