See patch.

Thanks everyone on IRC helping get this stuff debugged this far, and
especially Jakob Bornecrantz <wallbraker@gmail.com> for testing on
his VIA EPIA-M700!


Uwe.

Thanks, committed in r4426.

Also added the boot log to the wiki page:

Patch

Fix VIA EPIA-M700 target enough for a first serial boot log.

Add the respective Super I/O config in Config.lb (Winbond W83697HG),
enable COM1 on the board, fix irq_table.c, as well as the PCI
devices listed in Config.lb (based on lspci output).

This has been tested by Jakob Bornecrantz <wallbraker@gmail.com>
on hardware, i.e. there is serial output. It does not yet boot
to a Linux console successfully, more fixing will be needed.
