just checking but you realize that I will have to modify env/ext4.c to 
use these new CONFIG_ just like we do for FAT?
for EXT4 we were using include/configs/.h instead as described in the 
commit (so the feature was fully functional, just slightly different to 
FAT when defining the variables).

ok?
