TMDS64GPEVM: PCIE RC access 4GB EP memory

Part Number: TMDS64GPEVM

Hello,


I'm using PCIE in the following configuration : AM64 RC (A53 Linux) <-> AM64 EP (R5 Baremetal)

I want RC to access full lower 4GB of address space of EP :
   -  Do I need to define a BAR of 4GB in EP and map it one to one to Lower 4GB of EP ?
        In this case RC will need to use PCIE0_DAT1 and map outbound to (0x0-4GB). Is this supported on Linux driver ?
   - Or is there no need for EP to define any BAR ?

The reason why I want this : I want to be able to use a second AM64 as an extension of RC to expand first AM64 capacities


Thanks
