To allocate resources from the top.

There isn't one. I mean back to kernel's way. Why should U-boot use
different way from kernel to allocate resources since most PCI parts are
similar (equivalent) to kernel?

Yes, I know. Hopefully  not too much. This change will only change the
allocation direction. Once U-boot has same algorithm with kernel, it is
easier to maintain in the future.
