Firefly and Rock2 use an act8846 as pmic while your board seems to use the 
rk808. The switch used to control your vcc_lan is most likely off on boot 
while the regulator used on firefly etc is most likely simply on on boot.

I don't know if the devicemanager-part of uboot actually handles such 
regulator-supplies at all.
