FPDT data gives an approximation of how long each stage
of the firmware boot takes. Since the RPi has a generic
timer this is a fairly accurate timestamp from the point
where edk2 takes over, which is a few ms from actual
power on. While its not perfect its sufficiently granular
that a command like `systemd-analyze` shows the debug boot
to be quite slow.
Ex:
[root@rpi4 ~]# systemd-analyze
Startup finished in 24.313s (firmware) + 7.771s (loader) + 2.442s (kernel) +
5.810s (initrd) + 20.371s (userspace) = 1min 708ms
multi-user.target reached after 17.343s in userspace.
