systemd-analyze shows long firmware time with sd-boot

[Chris Murphy <lists@xxxxxxxxxxxxxxxxx>]

Hi,

systemd-243-2.gitfab6f01.fc31.x86_64

systemd-analyze reports very high firmware times, seemingly related to
uptime since last cold boot. That is, if I poweroff then boot, the
time for firmware seems reasonable; whereas reboots appear to show
cumulative time for only the firmware value.

This is in a qemu-kvm VM, using edk2-ovmf-20190501stable-4.fc31.noarch

reboot (warm boot)

$ systemd-analyze
Startup finished in 8min 2.506s (firmware) + 12ms (loader) + 1.414s
(kernel) + 1.383s (initrd) + 8.962s (userspace) = 8min 14.278s
