Subject: xpedite1k: Store environment in flash
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=767e32ad369d83f55f950e6938e68b6dba7fa65f;p=u-boot.git

xpedite1k: Store environment in flash

Previously an I2C EEPROM was used.  The EEPROM had size, reliability,
and access issues which are resolved by storing the environment in
flash.
