+
+Known issues:
+- Alpine Ridge Thunderbolt 3 controller does not work
+- Some Fn+F{1-12} keys aren't handled correctly
+- Nvidia dGPU is finicky
+ - Needs option ROM
+ - Power enable code is buggy
+ - Nouveau only works on linux 6.8-6.9
+- Headphone jack isn't detected as plugged in despite correct verbs
+
+Thanks to Leah Rowe for helping with the T480s.

+Subject: [PATCH 31/37] dell/3050micro: disable nvme hotplug
+
+in my testing, when running my 3050micro for a few days,
+the nvme would sometimes randomly rename.
+
+e.g. nvme0n1 renamed to nvme0n2
+
+this might cause crashes in linux, if booting only from the
+nvme. in my case, i was booting from mdraid (sata+nvme) and
+every few days, the nvme would rename at least once, causing
+my RAID to become unsynced. since i'm using RAID1, this was
+OK and I could simply re-sync the array, but this is quite
+precarious indeed. if you're using raid0, that will potentially
+corrupt your RAID array indefinitely.
+
+this same issue manifested on the T480/T480 thinkpads, and
+S3 resume would break because of that, when booting from nvme,
+because the nvme would be "unplugged" and appear to linux as a
+new device (the one that you booted from).
+
+the fix there was to disable hotplugging on that pci-e slot
+for the nvme, so apply the same fix here for 3050 micro

+Subject: [PATCH 32/37] lenovo: Add Kconfig option CONFIG_LENOVO_TBFW_BIN
+
+This is used by lbmk to know where a tb.bin file goes,
+when extracting and padding TBT.bin from Lenovo ThunderBolt
+firmware updates on T480/T480s and other machines, grabbing
+Lenovo update files.
+
+Not used in any builds, so it's not relevant for ./mk inject
+
+However, the ThunderBolt firmware is now auto-downloaded on
+T480/T480s. This is not inserted, because it doesn't go in
+the main flash, but the resulting ROM image can be flashed
+on the TB controller's separate flash chip.
+
+Locations are as follows:
+
+vendorfiles/t480s/tb.bin
+vendorfiles/t480/tb.bin
+
+This can be used for other affected ThinkPads when they're
+added to Libreboot, but note that Lenovo provides different
+TB firmware files for each machine.
+
+Since I assume it's the same TB controller on all of those
+machines, I have to wonder: what difference is there between
+the various TBT.bin files provided by Lenovo, and how do they
+differ in terms of actual flashed configuration?
+
+We simply flash the padded TBT.bin when updating the firmware,
+flashing externally. That's what this patch is for, so that
+lbmk can auto-download them.

+Subject: [PATCH 34/37] soc/intel/pmc: Hardcoded poweroff after power fail
+
+Coreboot can set the power state for power on after previous
+power failure, based on the option table. On the ThinkPad T480,
+we have no nvram and, due to coreboot's design, we therefore
+have no option table, so the default setting is enabled.
+
+In my testing, this seems to be that the system will turn on
+after a power failure. If your ThinkPad was previously in a state
+where it wouldn't turn on when plugging in the power, it'd be fine.
+
+If your battery ran out later on, this would be triggered and
+your ThinkPad would permanently turn on, when plugging in a charger,
+and there is currently no way to configure this behaviour.
+
+We currently only use the common SoC PMC code on the ThinkPad
+T480, T480s and the Dell OptiPlex 3050 Micro, at the time of
+this patch, and it is desirable that the system be set to power
+off after power fail anyway.
+
+In some cases, you might want the opposite, for example if you're
+running a server. This will be documented on the website, for that
+reason.

+The option was appearing in T480/3050micro configs of lbmk,

+
+CONFIG_DEBUG_STACK_OVERFLOW_BREAKPOINTS=y
+

+
+ soc/intel/pantherlake: Disable stack overflow debug options
+
+Well now:
+
+I'm disabling this behaviour on Skylake, for the same
+behaviour, because I want as few behaviour changes in general,
+as possible, for the rev8 release.
+
+According to Subrata's patch, which was for Pantherlake,
+without this change, stack corruption can occur on verstage
+and romstage early on. Please look at that coreboot patch,
+referenced above, for clarity.
+
+I see no harm in disabling this option for Skylake, since
+the behaviour that it otherwise enables was not present
+before.

+Otherwise, other boards will define it, which

+Subject: [PATCH 1/1] do not break building other thinkpads with the hacks for
+ the t480/s made Mate Kukri
+
+still not fixing things properly but at least it should now be possible to build older thinkpads without regressions.
+prior, some code was just commented or unreachable. now we make this explicit with preprocessor directives.
+heads should build all boards on this coreboot version from the same coreboot tree.
