MECP5123 is a MPC5121E based module by esd gmbh.
Signed-off-by: Stefan Roese sr@denx.de Cc: Reinhard Arlt reinhard.arlt@esd-electronics.com --- v2: - Fix indentation problem - get_ram_size() used - More documentation added - Copyright updated - Too long lines changed - Removed CONFIG_OF_SUPPORT_OLD_DEVICE_TREES
Wolfgang, I now have to explicit ACK from esd that this board shall use I2C EEPROM as environment storage.
