From: Eric Schumann E.Schumann@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.
