For the short term: Consider updating libpayload in your tree to the
latest version while keeping coreboot in your current state. This works
since these are really two independent projects.
However you will fare better long term by keeping your coreboot tree
close to upstream.

Hi Zoran,
Glad that you found the source of the problem!

If you are distributing coreboot then it would be significantly
easier for you to work with the community with the goal to have
your needed functionality available in the public coreboot git.
Like with other open source projects.
Kind regards

My guess is that the libpayload in your coreboot tree is older. FILO's
master branch was adapted to an i386->x86 rename in December 2012.
Please retry building FILO in a coreboot master checkout (so you get the
master libpayload as well). These are no ABI changes, so a FILO payload
built that way is still usable with an older coreboot tree.

Patrick

I don't know about your environment but it seems to me that the FILO
code is buggy. It is not so popular anymore so it's possible that
there is some bitrot. Hopefully you can help look into what the
problem is.

I'm not sure what you mean, but yes it has been possible to build
FILO in the past. If you can it would be great if you use git bisect
to find the commit which broke the build.

Hello to Coreboot community,
Went to filo Coreboot page: http://www.coreboot.org/FILO
As written, executed the following:
cd coreboot/payloads
git clone http://review.coreboot.org/p/filo.git
cd filo
make menuconfig
make produces several errors, on the way, so I did temporarily fix it:
[zoran@localhost filo]$ diff -c Makefile Makefile.orig

Any idea why this is happening? Did somehow I misconfigured coreboot/payloads/libpayload (it was compiled prior these steps)?

Can't you cache the ROM area?
Other than that: Optimizing the common code is better than a special
case. memmove won't change much, so that's a stable interface, but you
never know what will happen (and few people will be able to test their
changes on Vortex86).

They use the 6-series/C200/HM65 chipset. The public datasheet is here:
http://www.intel.com/content/www/us/en/chipsets/6-chipset-c200-chipset-da...
The newer products (Acer C7, Lenovo X131e, and HP 14-c050 Chromebooks) use
the 7-Series/C210 chipset. The public datasheet is here:
http://www.intel.com/content/www/us/en/chipsets/7-series-chipset-pch-data...
It's been a while since I've looked at the huge matrix of codenames for
those generations of chipsets, but IIRC Cougar Point is in there
somewhere...
BTW -- For your goals of PXE booting you might want to look into SeaBIOS (
http://www.coreboot.org/SeaBIOS) and IPXE (http://www.coreboot.org/IPXE).

ok thanks, that's a good lead.

Funny you should mention Stumpy and Lumpy since the source of firmware
one can download at coreboot.org git for these devices has been broken
for several weeks now.
Where can one download the sources and build toolchain for the firmware
images Google ships these products with? This looks a lot like license
terms violation to me, when customer cannot recreate the binary.
I think I have asked at #coreboot a couple of times how to track the
revision tags or commit hashes from a production image to the sources.
And have gotten no answer.
And to be clear, I am _not_ referring to the sources of the systemagent
binary blob of these Intel chipsets here.
