On D05 PCIe now, 2p NA PCIe2 and 2p NB PCIe0's pci domain addresses are 0x20000000 and 0x30000000 based. These addresses overlap with the DDR memory range 0-1G. In this situation, on the inbound direction, our pcie will drop the DDR address access that are located in the pci range window and lead to a dataflow error.
This describes the problem, please also describe the solution. Looks to me like you are shrinking the sizes of the regions.

Leif
