[PATCH] Add CBFS support to FILO

[Patrick Georgi]

Hi,

attached patch adds CBFS to FILO. Use mem:/path/to/file for access.
Tested with
configfile mem:/menu.lst
after I added with
cbfstool coreboot.rom add menu.lst menu.lst 84

The filetype ID (84 in this case) can be freely chosen as long as it's not 0

Hi,

Attached is an update to Patrick's filo patch, with a small patch to
libpayload too.

In addition to basic CBFS file system support, which should allow
configfile and linux boot from CBFS, I have also added initial SELF boot
support that allows simple libpayload based payloads to be launched from
filo.

Tested with ::
filo booting as default payload from SeaBIOS, then from filo command
prompt::

'configfile mem:filo/menu.lst' and also filo built with
mem:filo/menu.lst as default, after adding with::

'cbfstool coreboot.rom add filo/menu.lst menu.lst 84'

mem:filo/menu.lst contained::

#
# epia-n menu.lst for FILO
# Created 13/07/09 Jon Harrison 
#
default=0
timeout=5
title Fedora (2.6.25-JH)
    root hda1:
    kernel /vmlinuz-2.6.25 ro root=/dev/sda5 acpi=force
console=ttyS0,115200n8 debug
    initrd /initrd-2.6.25.img
title FILO (CBFS Payload)
    payload img/filo

I was able to boot img/filo image from filo, it sucessfully restarted
and reconfigured everything and went on to boot a full linux distro from
the version of filo booted from filo !!

The attached terminal output shows coreboot starting SeaBIOS with
autoboots filo, you can then see filo booting filo and the linux distro
starting normally with ACPI etc still intact.

I know a lot of you guys think that this is all a bit of a waste of time
/ broken way of doing things, but for me it does now mean that I have
the full equivalent functionality of SeaBIOS with USB keyboard support
all for only the cost of a compressed filo image.
