It would be nice if we could test coreboot images in VirtualBox, see
http://virtualbox.org/.
VirtualBox does not (yet) provide a simple mechanism to use a different
BIOS in their emulated machines (something like "-L" in qemu). Instead the
BIOS image (a custom bochs BIOS + LGPL'g VGABIOS) is converted to C code
(an array of bytes, or the like) and merged into the VirtualBox
executable.
The relevant files are
{{{
src/VBox/Devices/PC/DevPcBios.cpp
bldprogs/bin2c.c
}}}
if someone want to hack VirtualBox to easily support using coreboot images
instead of their usual BIOS.

EHCI debug port finder
by Carl-Daniel Hailfinger
I wanted to know which physical port of my multiple USB controllers have
the debug capability. There was no way to find that easily, so I created
a tool which will do most of the work for the user.
Example output:
The following PCI devices support a USB debug port (says lspci):
0000:00:1d.7
The following PCI devices support a USB debug port (says the kernel):
0000:00:1d.7
PCI device 0000:00:1d.7, USB bus 3, USB physical port 1
Currently connected high-speed devices:
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M
|__ Port 2: Dev 20, If 0, Class=stor., Driver=usb-storage, 480M
The output can be improved, but it's a good start.
Regards,
Carl-Daniel

Dual SPI Flash adapter attempt 2.0
by Oliver Schinagl
Hi list(s),
Here's my second attempt at routing the previously mailed png of my schema.
It was a lot trickier to route then my previous version, but I think it
worked out!
As mentioned, S1 and S2 need to be shorted if U3 is to be omitted. RN1
should be 10k or ideally 100k, as Peter mentioned earlier.
Hopefully there's no obvious mistakes and can start working on
alternative layouts (so it is insert-able in different angles).
DRC Check fails on S1, S2 and U3. It thinks the distance is to shallow.
That said, DRC check passes when I set the copper width/distance to
7mil's instead of the current 8 mils.
I'm planning on having these PCB's manufactured by Seeed studio and
their minimal width is much smaller.
Minimum trace width: 6mil
Minimum trace/vias/pads space : 6mil
Minimum silkscreen width : 4mil
Minimum silkscreen text size : 32mil
I've used a grid size of 10mil and distances of 8 mils, as I didn't want
to rely on the minimum of seed. The silkscreen I positioned using a grid
size of 5 mil's however. Not sure what they mean with a 'minimum
silkscreen text size' however.
Anyhow, feedback greatly appreciated, so I can start working on
alternative layouts :)

fixed AMD SPI speed settings (leading to problems on E350M1/USB3)
by Stefan Tauner
Hi,
andor reported a problem where flashrom does reproducibly not work with
coreboot but does with the vendor BIOS
http://paste.flashrom.org/view.php?id=1614
Apparently it is related to fast reads and/or the frequency.
We have forced the fastReadEnable bit in the SPI_Cntrl0 from 1 to 0 and
also set NormSpeed in SPI_Cntrl1 to 16.5 Mhz (previously was 0 i.e. 66
MHz) in flashrom and the problem vanished.
Coreboot hard codes the fast read setting in
src/southbridge/amd/cimx/sb800/bootblock.c:
static void enable_spi_fast_mode(void)
{
u8 byte;
u32 dword;
device_t dev = PCI_DEV(0, 0x14, 0x03);
// set temp MMIO base
volatile u32 *spi_base = (void *)0xa0000000;
u32 save = pci_io_read_config32(dev, 0xa0);
pci_io_write_config32(dev, 0xa0, (u32) spi_base | 2);
// early enable of SPI 33 MHz fast mode read
byte = spi_base[3];
spi_base[3] = (byte & ~(3 << 14)) | (1 << 14);
spi_base[0] = spi_base[0] | (1 << 18); // fast read enable
pci_io_write_config32(dev, 0xa0, save);
}
Marc suggested that this should be configurable in the devicetree or by
a kconfig setting. Also, the statements using "byte" do not make a lot
of sense to me. Shouldn't that be a u32 instead?
The public documentation of the fastReadEnable is lacking any detail
and I don't have access to the NDAed version of the RRG. Is my theory
correct that the controller uses the 0x0B opcode with a fixed frequency
(33 MHz?) instead of 0x03 with the frequency set by NormSpeed?

-----------------------------------+----------------------------------
Although (or: just because) novice in the field, I encountered some
problems with netbooting with coreboot.
Mobo's tried: Asus P2B, VTech with bios id ITE8671-2A69KV3IC-00. All
mobo's boot '''harddisk''' fine with Asus P2B / Gigabyte GA-6BX{CE}
respectively.
NIC ROM is started, and loads the kernel by tftp. This is vvvveeeerrrryyy
slow! Although loading, the kernel is never able to start itself. Same
kernel on HDU is no problem at all (GRUB2)
Note: the gpxe-image is on the nic, coreboot payload is seabios.

Hi
I have question related to libpayload, which I am trying to solve, but not
able to.
I have successfully build the coreboot.rom for QEMU x86.
Now when I try to build the libpayload project it throws error.
System configuration:
Virtual Box –Ubuntu 11.10 version
Building for X86 Paltform
Earlier I have run the cross toolchain using the command ‘make crossgcc’
and it was succcessfull
Error information:

pradish@pradish-VrtualBox:~/coreboot/paylaods/libpayload$
can you tell me, how to resolve this , I have not done any changes to the
source code. Just performed ‘make’

Re: [coreboot] Samsung 550 Chromebook own Coreboot
by John Lewis
After some toing and froing with Aaron Durbin over the last 6 hours
this is where we are:
mrc.cache is now working but cold boot still takes roughly 5 seconds to
get to SeaBIOS display. Warm boot/reset is instantaneous. Aaron says the
mrc.bin blob is not happy (and we can't have an unhappy blob now, can
we).
In order to get mrc.cache working this is what's required:
1. Remove 'select CHROMEOS' from src/mainboard/samsung/lumpy/Kconfig.
2. Add this patch:
diff --git a/src/vendorcode/google/chromeos/gnvs.h
b/src/vendorcode/google/chrom

3. make oldconfig

5. make (obviously)
Additionally, to get timing information in cbmem -c and cbmem -t the
following was necessary:
1. Add 'select LAPIC_MONOTONIC_TIMER' to
src/mainboard/samsung/lumpy/Kconfig
2. make oldconfig
3. make (again obviously)
The cbmem output is attached. Where to go from here? Many thanks to
Aaron for all his help.

Generate microcode from tree not working
by Alec Ari
Hello! Someone recently contacted me directly about my MA785GM-US2H coreboot port, and they weren't able to get the microcode to generate:
HOSTCC cbfstool/cbfstool (link)
LD cpu_microcode_blob.o
coreboot/util/crossgcc/xgcc/bin/i386-elf-ld: no input files
make: *** [build/cpu_microcode_blob.o] Error 1
I've tested the compilation process here too and I get the same problem, not sure how to fix it. It doesn't work for me no matter what board I select in Kconfig.
Please note I am not subscribed to the coreboot mailing list so if you have a response, I kindly suggest you CC the email to me directly.

Your cold logs has the following:
find_current_mrc_cache_local: No valid MRC cache found.
I take it that was after a fresh reprogram? If you do another cold
boot it should use the MRC cache.
I was going to compare the boot state times, but it seems these logs
don't have CONFIG_LAPIC_MONOTONIC_TIMER enabled?
