Hello Stefan,

>> Signifacance of CONFIG_EXTRA_ENV_UNLOCK:
>> This env variable is read by the cfi driver to unlock all flash sectors.
>> This is necessary because the Parallel NOR flash connected on the spear

Ok. I would undefine it from the spear-common file and define it for 
SPEAr310 board file only.
