we have 4 EP devices each have 8MB access requirement.

but i can read from manual "PCIe max memory alignment is 16MB for i.MX 6 quad."

 

Can i.MX 6 access 4 EP devices each have 8MB ?

 

In iATU, it can has 4 regions. then

first iATU set : 8MB  for first EP

second iATU set : 8MB for second EP

third iATU set : 8MB for third EP

fourth iATU set : 8MB for fourth EP

is it possible ?
