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

flashrom patch: add support for Abit AB-BM6 board
by Tim ter Laak
Hello all,
This patch adds support for the Abit AB-BM6 mainboard to flashrom.
The biggest part is a generic function to lower a GPIO line on the PIIX4E
southbridge, copied and adapted from its ich_gpio_raise() counterpart
(mostly lower instead of raise, followed names from the PIIX4E datasheet).
The board specific function then uses this to lower GPO 26.
Signed-off-by: Tim ter Laak <timl(a)scintilla.utwente.nl>
---
The patch was made from the flashrom subdir, because svn diff from the
top-level coreboot dir (as per the directions in the Development
Guidelines on the wiki) didn't seem to work for me. Probably because
flashrom is fetched externally when checking out coreboot? Anyway, I hope
this is okay. If you really prefer a diff from the top-level dir just let
me know, and I'll regenerate it with gnu diff.
Kind regards,
Tim.

Hi,
Why is it problem to boot from an usb port when we are using linuxbios and
filo. as I can see all usb code are there, what is missing?
Thanks,

There isn't much SeaBIOS info in that log - can you recompile with
CONFIG_DEBUG_LEVEL set to 6?

Without tables in high memory, seabios won't run on your chipset properly.
it overwrites your tables in the F segment, as seabios itself lives there.
Also, once there is support for high_tables_base everywhere, the code in
src/arch/i386/boot/tables.c can be cleaned up and simplified considerably.
