No, the network IP in the A370 and AXP is totally different and Marvell
engineers think it needs a new driver, and I have been making internal
reviews of their driver, but it needs more work before being ready for
submission.

A while ago, we had a discussion with Ben Dooks (from CodeThink) on
whether a new driver was needed or not. Ben will correct me if I'm
wrong, but he was suggesting that a new driver was not needed, but both
Marvell engineers and my comparison of the datasheets between A370/AXP
and older Marvell EBU SoCs clearly show that this IP has changed
dramatically, and is even not the same IP as before.

If needed, I can post the network driver code in a RFC state, but it is
clearly not yet ready for inclusion.

I would of course be happy to test SATA patches for the Armada XP. Ian,
did you reuse the plat-orion/addr-map.c code to do the window setup?

Best regards,

Thomas
