Do you have to use 2 cells for address? Cannot it be:
 			ranges = <0 0x04000000 0x20000
 				  1 0x05000000 0x20000
 				  2 0x06000000 0x20000
 				  3 0x07000000 0x20000>;

 I tried this first, but it didn't work, and ranges translation
gave me something really weird (like addr = 0x80 and
size = 0x04000004).

Did you change the address-cells to <1>?

 Of course i did.

I saw some other nodes use the ranges without the offset but maybe some
more steps are required for such configuration.

So anyway send the version with the child offset and I will try to
figure out why it is required.
