After I set CONFIG_USE_OPTION_TABLE, my laptop will power on when I plug in
the AC adapter. Then I find disabling `power_on_after_fail' will prevent my
laptop from booting when AC is plugged in. So I wonder why this setting is
called `power_on_after_fail' instead of `power on AC attach' as with the

I think making it depend on EXPERT is a great idea.
I'd also like the interface to be friendlier. What granularity is
actually supported for the option? I doubt that it's single bytes?
Maybe make it decimal kb? The default value depends on ROM_SIZE, right?

It's trivial to add another variable between the user interface and

The big difference is that users never see the actual ROM_SIZE value.
They see a friendly list of common flash chip sizes, with the default
being what ships with the particular board.

What are the common CBFS_SIZE values?
Dear coreboot folks,
commit f780c40f (CBFS: Correct ROM_SIZE for ARM boards, use CBFS_SIZE
for cbfstool)  adds a description to the Kconfig variable
`CBFS_SIZE`, which makes it, I think, visible in the Kconfig menu (`make

What section should
(0x400000) Size of CBFS filesystem in ROM
be moved to?
Furthermore, should it even be visible or be hidden as an expert option?
Dear Gerd, dear Greg,
sorry for the late reply.

The confusion could be solved in the mean time, but I still want to
After reading both of your replies to the test stand message, I was very
angry and disappointed about the bad assumptions you both made and the,
in my opinion, impolite style by using words like *spamming* and
For the future I wish that we first assume that the other side is
meaning well. So I should assume, both of you meant well too. But I just
wanted to get it out.
In the end, in my opinion, the Raptor Engineering Automated Test Stand¹
is the best contribution to the coreboot infrastructure since the
switching to a git based workflow. So big thanks to Raptor Engineering
¹ REATS is a strange acronym. Maybe a better name can be found. ;-)
welcome to coreboot!

if you select this option, build a coreboot based image and boot to
GNU/Linux, you can read the time stamps with `sudo cbmem -t`.
$ cd util/cbmem
$ sudo ./cbmem -t
> I want to collect all the timestamps of the drivers and to find out BOOT
What board do you use? Note, AMD AGESA boards currently do *not* support
storing romstage time stamps, so they cannot be read out and are lost
during the boot.
Also remember that the payloads, at least GRUB 2, SeaBIOS and FILO, do
not write store time stamps in CBMEM.
There is also timing information, which coreboot only puts in its
console log (`sudo ./cbmem -c`).
Search for *BS:* and *usec* for example.
Please report back, if that helped you.
PS: The official spelling of the project name is *coreboot*, that means
it’s one word.
I am new to this list.
I am trying to learn how to compile coreboot. My host has these:
---cpu: AMD64 3 cores
---OS: linux (BLFS) linux-3.10.32, ( pure 64-bit ), gcc-4.8.1. IASL (
downloaded as tbb41_201305160ss )
A ) I fetched coreboot fron the git repository
B ) I unpacked the downloaded in /usr/src
C ) I ran 'make menuconfig' and selected 'build with any toolchain'
D ) I then ran 'make' which ended as follows:-
mv build/coreboot.pre1.tmp build/coreboot.pre1

I am running on a pure 64-bit host but it seems coreboot is attempting to
link 32-bit binaries. Help to successfuly build coreboot will be
