Hi! I'm new to this list so I'll start by introducing myself a bit: I'm a french student involved in free software: I use GNU/Linux distros on all my PCs, mostly with the fully free Trisquel distro and I'm also a developer (I know C quite well) mostly involved in the Replicant project (fully free Android derivate) as a hacker (lower-level stuff).
The lead dev on the project (GNUtoo) decided to look at how doable it is to port his board to coreboot, so I decided to follow his lead and look at which of the motherboards I own would be the best one for coreboot. I have 2 boards that might be good candidates, ASRock ConRoeXFire-eSATA2 (which has a socketed PLCC32 chip) and Asus P5LP-LE (Lithium) with a soldered PLCC32 chip. Both boards should have supported North/Southbridge and SuperIO already supported in coreboot.
I decided to start the work on the ASRock ConRoeXFire-eSATA2 one and thanks to the help I got on IRC, it has been possible to add support for the board on flashrom in a few hours. I also found another compatible flash (same size, even same model apparently) so I can use it to flash coreboot images.
So here are the technical details now: * northbridge is Intel Corporation 82945G/GZ/P/PL * southbridge is Intel Corporation N10/ICH 7 Family * superio is Winbond W83627EHG (see lspci out for more details)
So the board coming closer to mine is Kontron 986LCD-M/mITX. I forked the device files for this one and I did this: * replaced W83627THG references to W83627EHG * used superio init function from another board (ASUS A8V-E SE) * modified this function to have clcksel to 48MHz (as told on IRC) * called w83627ehg_enable_serial(SERIAL_DEV, CONFIG_TTYS0_BASE); between superio init and console init
So far I got serial working, but the northbridge I use isn't the exact model on the board and the model on the board isn't supported by coreboot. Though: some stuff seems to work with the other northbridge code and I found wide documentation about the intel 945G/GZ/P/PL chip used.
So I'm wondering what the next steps are… Adding support for the correct northbridge?
