I have tested your patch set the following way:
Patches applied: - Got 4.7-queue from the SCSI repo - Applied the patch set for DW UFS support - Applied your patch set for RPMB support
Platform (UFS IP Prototyping Kit): - CPU: ARC CPU 32-bit - UFS 2.0 Core running in FPGA
Results: Kernel Build without RPMB configured: OK Kernel Build with RPMB configured: OK UFS Device partitions shown in UFS Host without RPMB configured: Yes UFS Device partitions shown in UFS Host with RPMB configured: Yes
I would like to run more verifications regarding RPMB. Could you tell me what is the procedure you suggest?
Thanks, Joao
