ufs-utils is a userspace tool for Universal Flash Storage (UFS) devices.
It reads and writes descriptors, attributes, and flags, sends UIC
commands, and drives RPMB and advanced RPMB.
On FreeBSD it reaches the device through the ufshci(4) passthrough
ioctl, which is in main only, and the CAM pass(4) device.
The FreeBSD support is pending upstream (SanDisk PR #83). Until it
lands, the port builds from the author's fork.
