It's not supported yet (AFAIK) but I think that it would be possible. 
It's not as easy as flashing the kernel partition because you have to 
write an "environment offset" pointer into the out-of-band data of the 
first flash block. This tells u-boot which block contains its 
environment variables, and this number is specific to each device due to 
bad blocks.
