see patch for rationale. this should prevent instability caused
when the nvme randomly replugs under linux. sometimes e.g. nvme0n1
becomes nvme0n2 while the system is running.
in my case, that caused my raid1 to become unsynced every few days.
this issue was fixed on t480 by disabling pcie hotplug for its nvme
device, so the same fix has been applied for dell optiplex 3050 micro.

this was done with the following command:
./mk -u coreboot t480s_fsp_16mb t480_fsp_16mb
it was set to 256 but should be 512. the SPD is what
contains configuration data for raminit, which training
code uses so that the timings will be correct. if the SPD
size is wrong, the machine won't boot
in practise, lbmk always runs "make oldconfig" on
a coreboot config, before building it, so this was
already being corrected automatically at build time.
however, if that fact ever changes in the future, this
wrong configuration would cause the machines not to boot.
therefore, this can be considered a preventative or perhaps
pre-emptive bug fix.
this fix does not need to be applied to the 20241206 release,
because of the behaviour described above. the final ROM images
do have the spd size set correctly to 512, because of this
design feature in lbmk.

the previous commit changed an mv to a cp. what it hacked
was actually a relic of the vgarom download patch that i
did for t480, before mate got native video init working.
this patch is the better fix. i double checked to be sure,
and nothing was using the files at the copied location.
the _extracted directory under cache gets deleted later on,
so it's perfectly acceptable to keep.
the other alternative would have been to simply change
the path in the sch5545 function to appdir, instead of
the cache dir, but who really cares?
this patch removes bloat from lbmk.

I should have copied the extract directory, in cases
where it appears as filename_extracted/ under cache/,
but I was moving it instead.
Both locations (cache/file/*_extracted/
and vendorfiles/appdir/) get deleted, on every run of
the vendor script, per target, so this is OK.
The only sin is additional use of disk space, for
archives that are mostly very small and get immediately
deleted anyway.
This one lbmk bug, minor though it may be, prevented
the Libreboot 20241205 release, which (since it's now
the 6th of December) will become Libreboot 20241206
instead - and that gives me time to contemplate whether
I want to do one more change that I had planned for the 5th!

Nope! Bootflow menu is cursed on this machine.
Too many issues in U-Boot on this machine. I did however
boot a Debian installer after it booted, using bootflow.
The installed system wouldn't boot with bootflow, but I could
then boot it with "bootefi bootmgr".
I'll rig up a uart on the T480 when I get round to it and
start investigating U-Boot bugs on this board.
I don't want people flashing something that doesn't work.
GRUB and SeaBIOS work, so ship those, and don't ship U-Boot.
This reverts commit 19ec440a6f.
u-boot does work after a few reboots. it just boot loops.
let it run. it should be able to boot from nvme. sata still needs
some work (sata only works in grub, on this machine)

The bootflow menu is already the default boot command on x86. Switch
arm64 boards to that as well, so instead of booting the first thing we

Otherwise, you have to press enter to boot your distro.
With this, a timeout is created. After a number of seconds,
which can be reconfigured, the first option selected will be booted,
when generating a bootflow menu.
The timeout is disabled when you navigate the menu; it only
kicks in if you don't input anything on the keyboard.
More information about how this works is in the U-Boot patches,
within this patch. I've set the timeout to 8 seconds.

Otherwise, you have to press enter to boot, which is unacceptable

Pressing anything other than enter an an option, such as the arrow

On coreboot for example, as Mate has told me, if you're
making Kconfig changes and re-compiling, sometimes the
actual image that you build might still have the old one
in it, due to how coreboot's build system works.
To mitigate this, you can just always run distclean before
doing the build, but lbmk was doing just clean.
In practise, we did not find any issues, but this change should
be harmless, and might prevent such issues in the future. It's
even possible that we might have already encountered this before
and not realised, and we were just lucky that no noticeable issues
were caused.
It's *also* possible that the reverse is true: an issue that
was previously covered up, then that issue will now be exposed.
However, if that turns out to be true, then that is good because
we are exposing said bugs and then we will know to fix them!
Anyway, the variable in target.cfg is:
cleancmd="whatever_you_want"
e.g.
cleancmd="distclean"
You may also specify this in global mkhelper.cfg files, per
project; I've already done this for SeaBIOS, coreboot
and U-Boot, since all of these use Kconfig files.

Patchset 20 from:
https://review.coreboot.org/c/coreboot/+/83274/18..20
Updated to that. A bunch of changes I made locally have been
copied here, thus removed from lbmk.
The previous setup in lbmk was to have only the DIMM slot work,
on the ThinkPad T480S, without setting up SPD for the onboard RAM>
Mate Kukri reverse engineered the scheme by which the SPDs are
chosen at boot, based on the wiring of the board. This should
just about match the way Lenovo did it in their firmware.

Libreboot's binary blob reduction policy is crystal clear:
If a blob can be avoided, it must be avoided.
The ThinkPad T480 was using Intel's VGA ROM for graphics
initialisation very briefly, before Mate fixed libgfxinit.
Since libgfxinit is fixed, the Intel VGA ROM is obsolete,
so we should not be handling this at all.
Similarly, the Nvidia ROM handling has been removed, because
Mate is hard-disabling that in the coreboot code anyway, since
the Nvidia dGPU didn't work when tested anyway.
Even if it did, Libreboot's blob policy makes it clear
that Intel graphics with native init from coreboot is to
be the preferred option.

I also enabled this on T480S, because otherwise SeaBIOS hung.
Enabling it shouldn't cause any harm on the T480, though Mate
did say that his machine seemed to work with my setup.
However, I believe that was when I gave him the ones that lbmk
built with the VGA ROM. Now it builds with libgfxinit, because
Mate was able to fix libgfxinit on this machine.

Added t480s delta to deguard, for MFS config.
Updated coreboot/next to latest t480 patch set,
which includes t480s. This porting was done by
Mate Kukri.
also includes experimental t480s support
Also added a data.vbt file (not in the gerrit patch)
for the T480s.
I had to turn on 8254 legacy timer on t480s, otherwise
SeaBIOS would hang. Same issue I saw on OptiPlex 3050 Micro.
Minor issue:
On S3 resume, nvme0n1 for example got renamed to nvme0n2.
This caused a crash if running Linux from the nvme. I confirmed
this via live USB distro. So this port will need some tweaking
before it can be considered stable.
Also uses libgfxinit, which Mate recently fixed. I'm
going to enable libgfxinit on regular T480 next.

We need to initialize the USB subsystem before we can use USB devices
like keyboards and external disks, by running `usb start`. Use the
PREBOOT config option to run the necessary command before U-Boot tries
to automatically boot anything. It's already enabled for boards other
than gru_kevin and gru_bob, so just update those two configs.

Set default U-Boot revision to v2024.10 and rebase patches on top of
that. The video subsystem now has switched to using the 'cyclic'
mechanism, so the code around one of the video patches changed a bit.
x86 boards were already switched to v2024.10. Update U-Boot for the
remaining ARM64 boards as usual:
- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)

Otherwise, if PATH was set before, it will be re-used
again in the next pass. We previously unset CROSS_COMPILE
to avoid using the wrong cross-compiler when switching to
another target within a multi-tree project such as U-Boot.
Well, PATH was also being set, to use coreboot xgcc first.
This is fine, but the next target may not use the same one.
This patch solves a similar problem to the following patch
which was mentioned above:

Since U-Boot must be inserted at a specific offset, it's
theoretically possible that other files might overlap, but
cbfstool will work around wherever U-Boot was inserted if
it was inserted first; we don't use specific offsets for
the other files.
This is technically a preventative bug fix, but it fixes
a bug that would probably never occur in practise.

The "normal" mode in lbmk is where no built-in GPU exists,
or no libgfxinit is used, and SeaBIOS is the first payload,
and SeaBIOS executes VGA ROMs (can't know if it'll start
in VESA or text mode).
U-Boot needs a VESA framebuffer or native coreboot
framebuffer to work correctly.

Same concept as SeaGRUB, but for U-Boot. SeaBIOS starts, but
has a bootorder file loading U-Boot first, from flash.
You can interrupt it with the ESC menu, to boot something else
in SeaBIOS, including GRUB.
With this, we can effectively provide extremely user-friendly
UEFI-first setups in Libreboot.
Take that, edk2!

This is a patch from Simon Glass. U-Boot clears the display
when it starts up, but was asking the VESA driver to do the
same, needlessly; this patch avoids the latter.
A further patch is also included, which provides a better
message when jumping into long mode on the SPL (64-bit) target,
dumping it on the serial console instead of using printf.
