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
