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