[coreboot] New Target - HowTo

[Radim]

Hello,
I'm interested in coreboot for year or two, but now I found older board which has all supported chips on. Some time ago, I found in documentation how to make add new target (mainboard), but now I can't find it anymore. Can you please point me to some documentations dealing with this process (creating Kconfig, devicetree.cb, ...)?

My board is:

QDI P6I440BX/B1 Brilliant - I

lspci output:

00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 02)
00:01.0 PCI bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 02)
00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02)
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01)
00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 02)

Very similar board is ASUS P2B, same chips but different vendor (bud PCB layout is very similar).

Flashrom is working, PLCC32 socket soldered on board, additional EEPROM prepared, so where can I start?

Thanks for any suggestions
Radim
