NVMe caddy in the remaining space would be how to go about it there. On the
regular T480, the existing caddy area could easily fit two NVMe drives.
Errata
======
On ThinkPad T480/T480S, headphone output works; the internal speaker is disabled
but audio is not automatically redirected to the headphone jack. This switching
can be done manually, for example in the `pavucontrol` utility:
Output Devices -> Select Headphones on the built-in audio.
Pavucontrol will specify that the headphones are not connected, but you can
select it anyway and it will work. This will be fixed in a subsequent revision,
and the corrected images re-uploaded to the existing Libreboot 20241206 release.

for reading, and have a wonderful day!
Revisions
=========
Revision 1
----------
A bug was found whereby `seabios_` images are created twice, This was fixed in
the revision `e3b77b132e6b5981c09bc1ce282afaae64058ab3`. This bug caused vendor
file insertion to fail on release images, because the `vendorhashes` file would
list the file twice, but one of the hashes would be wrong.
This is because the build system wrongly created U-Boot-only images first with
that name, because the `add_uboot` function in `rom.sh` unconditionally created
images with U-Boot in them; the function also creates ARM64 images, where U-Boot
is the primary payload.
On x86 machines, SeaBIOS should be the main payload, chainloading U-Boot.
The build system would then create the actual `seabios_` image, replacing the
other one, on x86 machines.
So, the command to create the first image was removed. However, just before
uploading `rev1` images, it was discovered that this would cause no U-Boot
images to be built for ARM64 devices, which lead to Revision 2:
Revision 2
----------
See commit ID `b910424b5df8ed7c931a7b8f5cc8e34eacf0ca3e`.
Revision 1 was reverted, and replaced with the following logic instead:
In `add_uboot`, the instruction to create a ROM image was changed so that it
only creates one where U-Boot is the primary payload (which is the case for
ARM64).
The source archive is now `20241206rev2` instead of `20241206`, and the same
is true of affected images on x86, where `vcfg` is set in `target.cfg`.
