Ivy Bridge desktop support

[Nico Huber]

Dear coreboot folks,

I'm looking forward to write a port for my Ivy Bridge desktop system based
on this board: Intel DH77EB (codenamed Eb Lake, [1]). It comes with the H77
platform controller hub (PCH) and a Winbond W83677HG super I/O chip (build
by Nuvoton as NCT6775F, [2]). I'm using it with a Core i3-3225 processor [3].
I've got the datasheet for the super I/O, so writing support for it should
be no problem.

Is there any doubt that the current code for Ivy Bridge and the Panther Point
PCH works out of the box on a desktop system? I see that at least I have to
add some device IDs.

Regarding the PCH code, is SOUTHBRIDGE_INTEL_C216 the general option for
Panther Point? or is it really C216 specific?

Then there are the binary blobs. I'm not quite sure, which are necessary:
`ifdtool -x` gives me four regions out of the original vendor firmware:
  flashregion_0_flashdescriptor.bin,
  flashregion_1_bios.bin,
  flashregion_2_intel_me.bin, and
  flashregion_3_gbe.bin.
Obviously, the second one will be replaced with coreboot. I guess, I'll need
to use or replace the flashdescriptor.bin and intel_me.bin? What about the
last one `flashregion_3_gbe.bin`? do I need it as well? I haven't seen an
equivalent in the 3rdparty directories for supported boards. Surprisingly, I
didn't find a VGA BIOS in there. Well, I might not need it, anyhow. The box
should be booted before any display device is up :)

Regards,
Nico

Hi Nico,

I think that is is doable, but you will need to leverage the mrc.bin from
the current boards. I think that the chipset is fairly generic, C200.

The gbe.bin is for the integrated ethernet. I don't know what it does.

awesome news! Best luck with this!

The ASRock E350M1 [4] also uses the Nuvoton NCT6775F. Currently the code
from the Winbond W83627HF [5].

device pci 14.3 on # LPC        0x439d
        chip superio/winbond/w83627hf

Serial works for me. The only problem that might be related from any
incompatibilities is, that a PS/2 keyboard connected to the shared PS/2
port does not work correctly, meaning, entering a character the
characters is displayed several times more. Entering »n«, I get
»nnnnnnnn« for example. Alvaro, having a ASRock E350M1/USB3, also uses a
PS/2 keyboard *but* has no problems with this at all. So I have no idea
if this is related to the Super I/O or not.

Additionally the ACPI/ASL snippet provided for it has also some
problems.

That's me :D. Apparently my PS/2 keyboard works completely fine except 
for a weird thing. Sometimes, just after flashing, my keyboard will 
totally change its mapping: pushing "a" will give an "h", pushing "s" 
gill give a "["... with certain dominance of brackets, 'h' and 
backslashes... If I shut down the machine some minutes or reboot a 
handful of times, this will go away until next flash. Or maybe the 
second or third next flash. ¿¿??

Thanks

This is [6].

This is [7].

Please note that Martin Roth pointed out to me, that when looking at the
the ASRock E350M1, one actually finds that the Nuvoton NCT5572D is used.
Both superiotool and Linux’ w83627ehf are incorrect.

superiotool r4.0-3888-gce9f8be
        Found Nuvoton NCT6775F (B) (id=0xb473) at 0x2e

And if you know what you have to look for, you also find that this was
known all time along [8].

The board has a socketed SPI flash BIOS chip and a serial port
        header. The SIO is Nuvoton NCT5572D. Using coreboot's existing
        Winbond w83627hf is a good enough match to get the serial port
        and keyboard working.

Thanks,

Paul

Sounds weird. But something I can't test / run into: My board doesn't even
have a PS/2 port.

Uh, does this mean that both chips share the same ID? I get the same output
from superiotool:
    Found Nuvoton NCT6775F (B) (id=0xb473) at 0x2e
My chip is labeled W83677HG and I vaguely remember that I saw on a web page
that this is a NCT6775F. But I can't find the page anymore :(
Also, W83677HG sounds more like NCT6775F than NCT5572D.

Nico

They are probably the same chip. http://en.wikipedia.org/wiki/Nuvoton
Nuvoton was spun off from Winbond a few years ago. It's all just
branding and part number differences, I suspect.
