Yes I had faced problem with VGA bios for Atom Z520 platform due to the
interrupt dependency. so had to move graphic init to SeaBios.
Also VBT is good option since you are already using fsps for silicon init.

Hi,
Personally, I would recommend to use the FSP GOP, which should/could work with
even the stock VBT in "*FspBinPkg/SampleCode/Vbt/". You can also customise it
for your board using Intel BMP (Binary Modification Program) available online.
However, if you want to use the VGABIOS, you shouldn't n
Hi,
If the verbs are not enough, you might want to try searching for the
azalia function reset verb in the vendor firmware, using UEFITool, for example.
I know of at least my laptop, as well as one or more Thinkpads, that needed the
additinal verbs there (not in Linux's "init_pin_verbs") to get the

This means you're going to use libgfxinit instead of a video BIOS.
libgfxinit is a graphics modesetting library written in SPARK, a
OK, so that isn’t the way I want to go (I don’t think). Using the
romheaders utility on the file I have extracted gives me:

Looking at kconfig, the mainboard should select
MAINBOARD_HAS_LIBGFXINIT.
For example see "grep -rsn MAINBOARD_HAS_LIBGFXINIT src/"
I haven't used this, so not sure what else might be needed.
In order to get the build to progress I have needed to select
MAINBOARD_HAS_LIBGFXINI
Looking at kconfig, the mainboard should select MAINBOARD_HAS_LIBGFXINIT.
For example see "grep -rsn MAINBOARD_HAS_LIBGFXINIT src/"
I haven't used this, so not sure what else might be needed.

2. Open file ->
vim src/drivers/intel/gma/Kconfig +90
Add like so that it looks like:

So, I have made the change to src/drivers/intel/gma/Kconfig and when I
run the build it now gives the error:

Hello,
Using the instructions in the old Wiki page [1] I have used the UEFI method and
UEFI tool to extract the video BIOS from the standard binary that comes with
the board.
I have followed the layout of some of the other Kconfig files in the mainboard
directory and added the following to my
It's possible that there are different device ids. Example for baytrail
there are multiple ids.
You need to add the did specific to your soc & build flashrom & use that.
Did you figureout where is BIOS_CNTRL.LE bit is getting set. FSPS or in
Coreboot ?
We need to prevent the bit from setting.

Naresh,
Regarding adding support for denverton soc in flashrom, I could see a patch
in flashrom but device id seems to be incorrect one. Any comments on this
patch, as per soc device id should be 0x19e0.
