I assume rest of feedback could still be ignored. I am not going to check. It's your duty to implement the comments, not mine to check every line whether you did it or not. Trust does not work like that. Best regards, Krzysztof
Hi all, We took a step back. We are doing internal review ongoing on this patch-set. Thanks everybody helping me improving the patch series. Thanks.

This driver is enables communication ensuring well defined message sequence protocol between Application Core and enclave's firmware. Driver configures multiple misc-device on the MU, for multiple user-space applications can communicate on single MU.
