[coreboot] R4389 Adds EPIA-N(L) C3/CN400 Support - Developer Notes

[Harrison, Jon (SELEX GALILEO, UK)]

Dear Corebooters !

R4389 has added initial support for Via C3/CN400/VT8237R based EPIA
boards.

This should cover EPIA-N, EPIA-NL and also some of the low end EPIA-SP
boards.

The build has been tested on a Via EPIA-NL 8000 fitted with 1GB DDR400
SDRAM.

Current notes for the build for anyone seeking to develop further are as
follows::

1/ You need the VGA BIOS from factory BIOS and BOCHS to support the VGA
init, as described in the EPIA-M/II HOWTO.

2/ ACPI is completely untested

3/ At this point the build does not actually get through the payload
launch stage (may be a coreboot tables issue)

The spew level output is attached, for reference for what to expect if
you're working with epia-n.

I'm working now to get FILO launching and then get ACPI working.

Thanks,
Jon
