Was the old attempt a port or an implementation from scratch?

Any idea of of how close to "the u-boot way" the Linux driver is? I
haven't started looking at it yet.

I might need to do something expedient for my needs right now and come
back to doing a proper port later. The Marvell one is at least
implemented for u-boot, albeit v2013.01 and with their horrible USP
style. But if the port from Linux is relatively trivial it might be
easier to do than to catch the Marvell code up with 2 years of u-boot
development.
