Thanks. I would already be wonderful if I could merge many of those
preparations patches for 3.9.

That's fine, the problem is difficult, so it's expected to be difficult
to find the right solution.

However, I'd like to get serious alternate proposals when the current
proposal isn't considered appropriate. A serious proposal needs to
provide a mechanism to dynamically assign range of addresses to the
different BARs of the different PCIe devices, and those range of
addresses must comply with the special alignment requirements of the
Marvell address decoding windows. So far, I haven't seen any alternate
proposal that has those characteristics. The only alternate proposals
were based on static assignments of addresses to each PCIe interface,
which is unacceptable.

Thanks!

Thomas
