AM2434: Need the detailed information of ATU register of PCIe module

Hi,

We've received a question about ATU register of PCIe module from my customer. Could you help to answer their question below ?

When the PCIe driver defined on sysconfig operates, it seems that it sets the register group of the function called ATU, and this seems to be the part that affects the contents of the TLP, but there is no detailed description in the Technical Reference Manual for the ATU register.

Can they get the detailed information of the ATU register ?

They found the similar inquiry in the E2E forum below, but the ATU information was not disclosed on the forum, It seems that the information is disclosed only to the questioner.

Is it possible to tell them about the ATU configuration information?
