I got this wrong. I mistakenly thought we only had 4MiB of flash, but
we have 8MiB. So, it is reasonable to put two kernel images in flash
such that one is a backup in the event that the main one fails.
Once we get the second stage working properly, I'll implement
something so that the user can switch to a backup image by holding the
power button (or something like it) during startup. This means we'll
have 7.5 MiB/2 for each kernel w/initramfs which I hope is enough.
