ok, so i have a small update on this already: the driver is there and is 
working in the sunxi-3.4 branch, i built all the pieces in the kernel and i 
now have from
/dev/nanda to /dev/nandj
nanda is the boot partition, nandd seems the ext4 root, nande a 512m vfat 
partition, nandh and nandi empty ext4 ones, nandj a 2gb vfat one.
all the other seems to not be accessible

i suppose this layouthas to be maintained? (the space is very fragmented, 
doesn't let much storage space in the end
