Please find attached patches to restore the functionality of the
EPIA-N(L)/CN400 build, after the recent change to CBFS. This patch fixes
the build for loading VGA/BOCHS during VGA Init.

I've tested this against R4553 and EPIA-NL8000EG.

Features Tested as Working using FILO 0.6.0 Payload launching Fedora
Core 9 (2.6.25 kernel)::
VGA Console / X
SATA (As Boot device)
PATA CDROM (Autodetect/Mount/Eject all seem to work)
USB (keyboard, mouse and USB Flash Disk)
ACPI (S0/S5 Soft-off Works OK, Linux PM Seems to be working, PCI IRQ

Legacy Keyboard/Mouse have NOT been tested, but should work based on
existing VT8237R work.

Boots to FILO in ~1 second. FILO USB Keyboard/Mouse Support tested as

I've also attached a log of the boot console output.

cn400-src-v9.patch should be applied at src level
cn400-targets-v9.patch should be applied at targets level

Signed-off-by: Jon Harrison <bothlyn at blueyonder.co.uk>

The change itself is a bit of a hack to get things up and running again.
Discussions with Patrick suggest that the way that I'm doing the VGA
Init, based on the rather elderly epia-m build, is
obsolete/anachronistic as there is stuff in the core functionality to
the same job perhaps a bit more cleanly. I don't really have the time at
the moment to sort this out, perhaps someone else will have a look if a
working build is out there ?
