disable 3050micro nvme hotplug

2024-12-11T01:11:08+00:00

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.

fix t480 spd size (512, not 256)

2024-12-10T23:48:41+00:00

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.

Revert "Revert "disable u-boot on thinkpad t480""

2024-12-05T13:01:31+00:00

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 19ec440a6f79dcbb089715fef814808a0fd40ae0.

Revert "disable u-boot on thinkpad t480"

2024-12-05T09:55:06+00:00

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)

This reverts commit cd9baca5d664d392316d94ccaa7deb209d4e1828.

add patch from mkukri fixing t480 sata

2024-12-05T09:33:51+00:00

nvme worked but not sata. with this, t480 users with sata
ssds should be able to boot linux nicely

it's green there. different colour scheme apparently.

still works on x86. alper said his kevin chromebook was green!
