From: Eric Schumann <e.schum...@phytec.de>
On the pcm030 the environment is located in the onboard EEPROM. But we want
to handle flash sector protection in a safe manner. So we must read the
unlock environment variable from EEPROM instead from flash.
This patch is required as long the evironment is saved into the EEPROM.
