The background for the same is, 0xe0000000 onward memory space is allocated for IO register space so we are restricting the driver buffer allocations to 0xe0000000 - 1. Based on the comments received in the past, we are using GENMASK to generate 0xe0000000. Does this answer your query or I missed something? Thanks, Dikshita > Thanks, > Mauro
