As this patch enables the 32bit build of driver in meson, can you please add comment log that 32bit driver is not functional yet? Or maybe meson update can be moved to short doorbell patch, where driver becomes functional for 32 bit, this patch can mention in commit log that is preparation for 32 bit support, what do you think?
