5 Description:
6                 RPMB frames can be routed to the RPMB device via the
7                 user-space daemon tee-supplicant or the RPMB subsystem
8                 in the kernel. The value "user" means that the driver
9                 will route the RPMB frames via user space. Conversely,
10                 "kernel" means that the frames are routed via the RPMB
11                 subsystem without assistance from tee-supplicant. It
12                 should be assumed that RPMB frames are routed via user
13                 space if the variable is absent. The primary purpose
14                 of this variable is to let systemd know whether
15                 tee-supplicant is needed in the early boot with initramfs.
