Great.
I did a simlar setup some time ago for a narrower use case:
I needed extremly fast reflashing times.
I only had:
* A stock parabola(A GNU/Linux distro based on Arch)
* Good kernel commandline(to reduce logging)
* A well configured grub.
* No password at all, even for getty.

You could gain a lot of time by obtimising DHCP [1].
I've no idea about wpa_supplicant though.
You could also replace the sleep by something better: you could look if
you can get the status of the network connection somehow:
* Maybe trough dbus, but using dbus may slow down the startup.
* Else simply launch the browser with the right arguments once the
network is there.
You'll have to find the right arguments for that, so it remains
usable if the network comes and go.

How many miliseconds would be saved by putting grub.cfg directly inside
grub's coreboot.cfg?

Hi David,
Thanks for that. Perhaps I phrased the question wrongly. I guess what I
should've said was I'm not sure if you're still at the uni or gone to
some pub. :)
Thanks,
John.

I arrived. I guess I missed David and Ron @630. I'm hanging out in the
lobby if anyone wants to go eat.

Do you know where the default alignment is coming from? What
ramstage.o did you look at? What did the symbols say for these
objects? Are the sizes for the OBJECT types set to 20 for sure (I'd
expect it to be)?
The following could be related:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61296
We might be playing whack-a-mole and need to align all of our special
sections up to a typical cacheline (64) in the linker scripts. Or we
switch all of our objects in special sections to be pointers to
objects so that we can pointer align them.
