[U-Boot] Ease of porting Linux drivers/features to U-Boot?

I'm still trying to figure out how to get support for my AR7-based board
into U-Boot. There is support for the board in Linux, but some
fundamental pieces are missing from U-Boot.

E.g. support for the VLYNQ bus that connects the network interface to
the CPU, at the very least.

How difficult is it to port such things from Linux to U-Boot? Is it as
simple as copying files from the Linux sources, and a little glue to
enable linking them in (similar to how the UBIFS stuff has been
introduced), or is it a lot more complex than that?
