Linux/TMDXEVM8148: PCIe u-boot Memory Map Configuration

Part Number: TMDXEVM8148

Tool/software: Linux

Hi,

I am working with a design that is expected to boot Linux over PCIe.  I have built PCIe u-boot and am looking for the memory map configuration used.

I am referencing dm8127_TechRef_sprugz8g.pdf.  In this document the following registers are called out for use in configuring the PCIe memory mapping.

IB_START0_LO

IB_START0_HI

IB_OFFSET0

PCIe u-boot does not configure these registers. 

This being the case, what is the default memory mapping associated with PCIe u-boot?

Is the root complex expected to configure this mapping?
