32-bit Physical Addressing in T1042D4RDB

Hello,

 

My question is about physical addressing of T1042D4RDB. My board has 36-bit physical addressing, that means TLBs are created with 32-bit EPN and 36-bit RPN values, LAWs have 36-bit physical addressing as well.

 

u-boot and Linux certainly use 36-bit physical addressing on the board, but i wonder whether using 32-bit physical addressing is possible in the board.

 

Can i run u-boot or Linux with 32-bit physical addressing, create 32-bit EPN and 32-bit RPN TLBs for the board? Or, must all pyhsical addressing absolutely be 36-bit for the board?

 

Thanks in advanced.
