Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.
