That looks like not a production use case. USB + NET + drivers + EXT4 + NAND + MTD and everything else and trying to fit into SPL. With enabling LTO I still need 4k (without dropping current code). From one point it's too synthetic use case here and might be a historical limitation which we will not see on future boards. From the other point it will be good to not break it somehow....
