To me, that's a function of how complex the changes are and how
you describe them in the changelog text: If you have a lot of changes
for the merge window, having one branch per firmware type probably
works best, or even multiple ones if you have a series that implements
something new and a number of random changes do existing code.

If you have only a handful of bugfixes across multiple firmware
subsystems, a single 'firmware fixes' is less work for all of
us, with no loss of readability in the git history.
