mb/yanling: Add Yanling YL-KBR6L mainboard + doc
The Yanling YL-KBR6L (aka Yanling N18) is a Protecli FW6 with a newer CPUs (i5-8250U), different SuperIO chip (ITE IT8613F), slightly different (newer?) flash memory chip (MX25L6436F) and support for a mPCIe modem.
Working: - USB 3.0 front ports (SeaBIOS, Linux and FreeBSD) - 6 Ethernet ports - HDMI port with libgfxinit and VGA Option ROM - flashrom - PCIe WiFi - SATA and mSATA - mPCIe Modem in mSATA slot (tested with Simcom SIM7100E mPCIe) - Super I/O serial port 0 (RS232 via front RJ45 connector) - SeaBIOS payload (version rel-1.14.0) - Booting Ubuntu 20.04, FreeBSD 12.2 - 64GB RAM (tested with Crucial CT2K32G4SFD8266)
Untested (same as Protectli FW6): - Internal USB 2.0 headers - Boot with cleaned ME
Misc: - Removed "ProbelessTrace" in devicetree as done for other boards by coreboot.

One +has to remove all screws (in order): 4 top cover screws, 4 side cover screws +(one side is enough), 4 mainboard screws, 4 CPU screws (under DIMMs). Lift up +the mainboard and turn around it. The flash chip is near the SoC on the DIMM +slots side. Use a clip (or solder the wires) to program the chip.

This issue was present also with vendor BIOS. +- Sometimes FSPMemoryInit return errors or hangs (especially with 2 DIMMs + connected).

Patch Set 1:
Hi,
First time patch contributor, longer time user as I got an PC Engines APU2.
I was in contact with Michal Zygowski after I bought this Yanling N18/YL-KBR6L since I assumed that it's very, very close to the Protectli FW6. Looked like it was indeed the case and not too many modifications were necessary.
I have to add that I'm neither a firmware nor an embedded developer but a Linux Admin.
The code for the SuperIO is from Protectli vault_bsw and the rest from Protectli vaul_kbl. With changed device ids for video and LAN, of course.
I'm not sure if I have credited 3mdeb/Protectli enough and if not what should be added?
Cheers Thomas

Cheers Thomas
To me it is enough to be mentioned in board documentation. Anyway 3mdeb and Protectli is in the AUTHORS file, so there isn't any distinction about single files now.
First and foremost: does it boot well?

Patch Set 1:
Is it close enough to the Protectli FW6, so it could be added as a variant?
I assume it is close enough to be a variant of Protectli. My thinking was that if someone would have bought that Yanling computer she wouldn't look under Protectli for the mainboard source. And what name would we give that model?
Personally I think Protectli will get this and the faster model with i7-8550u cpu sooner or later.
While being in contact with Yanling because I couldn't get the 4G modem working with the stock firmware, they showed me screenshots of that it worked for them. The name of the Ubuntu workstation was 'ubuntu-FW6E' and the CPU was an i7-8550u. It certainly fits Protectlis naming. That would make this the FW6D model.
But adding it without the OK from Protectli or 3mdeb seems wrong to me.

Hi Paul,
Thanks a lot for commenting.
Yes, I do have ULRs which are in the markdown document. I'm indeed not a big fan of URLs in commit messages, too. Since they are often longer then 75 chars.
Would it be enough to add a reference that the links can be found in the documentation?
https://review.coreboot.org/c/coreboot/+/48769/1//COMMIT_MSG@15 PS1, Line 15: SeaBIOS, Linux and FreeBSD
For the record, can you please also note down the used version of these?
I'll do that, yes.
https://review.coreboot.org/c/coreboot/+/48769/1//COMMIT_MSG@17 PS1, Line 17: VGA Option ROM
Extracting and adding vbt to the commit is also an option.
Most part of the commit message comes from the markdown document. And most of that is a one-to-one copy of the FW6 document.
That is one part of that. Maybe it's better if I remove all the parts which are already in the FW6 markdown and add only a reference to it?
To answer the question: I used 3mdebs VGA options rom, the download link which can be found in the excellent Protectli/3mdeb "coreboot-building-guide.pdf".
https://review.coreboot.org/c/coreboot/+/48769/1//COMMIT_MSG@18 PS1, Line 18: flashrom

I'll add the version.

As Michal correctly said, it's 2x 32GB. I was avoiding to make the lines getting to long but I see it add confusion. I'll add the "2x32GB".

To me it is enough to be mentioned in board documentation. Anyway 3mdeb and Protectli is in the AUTHORS file, so there isn't any distinction about single files now.
First and foremost: does it boot well?
It does boot very well, a bit too fast so sometimes an USB stick won't be recognized but that's expected I guess.
And there is one error in the boot log regarding PCH_DEVFN_THERMAL device not found (line 7), which I haven't looked into it yet:
``` 1: ME: Error Code : No Error 2: ME: Progress Phase : Host Communication 3: ME: Power Management Event : Pseudo-global reset 4: ME: Progress Phase State : Host communication established 5: ME: Power Down Mitigation : NO 6: ME: FPF status : unfused 7: ERROR: PCH_DEVFN_THERMAL device not found! 8: Finalizing SMM. 9: APMC done. ```

It works very well, yes.
Looking at the "7th-and-8th-gen" document from Intel which you mentioned in an email, Kaby Lake and Kaby Lake Refresh where in the same category.
Nevertheless I'll have a look at the AmberlakeFspBinPkg and compare the settings.

That is one of the parts which I took over one-to-one from the FW6 documenation.
I know nothing yet about GOP, had to look up what it means.
https://review.coreboot.org/c/coreboot/+/48769/1/Documentation/mainboard/yan... PS1, Line 40: The main SPI flash can be accessed using [flashrom].
Maybe clarify, that this also applies to the vendor firmware.
Again, part of the original FW6 documentation.
But yes I used to flash coreboot and the original firmware, although only the BIOS part.
So I should add that both coreboot and the vendor firmware can be flashed using internal programing?

You're right, as mentioned (way) earlier, it maybe better if I remove all the pure copy-paste from FW6 and only reference to the FW6 document.

Hey Michal,
That is good news. How are we going to proceed? Are you taking over? Should I change the platform name and vendor? The new models as variants in vault_kbl or create a new one, e.g. vault_kbr?
Or abandon this patch and you provide your fixed one?
