Running U-Boot from coreboot on Chromebooks
===========================================
U-Boot can be used as a secondary boot loader in a few situations such as from
UEFI and coreboot (see README.x86). Recent Chromebooks use coreboot even on
ARM platforms to start up the machine.
This document aims to provide a guide to booting U-Boot on a Chromebook. It
is only a starting point, and there are many guides on the interwebs. But
placing this information in the U-Boot tree should make it easier to find for
those who use U-Boot habitually.
Most of these platforms are supported by U-Boot natively, but it is risky to
replace the ROM unless you have a servo board and cable to restore it with.
For all of these the standard U-Boot build instructions apply. For example on
ARM:
sudo apt install gcc-arm-linux-gnueabi
mkdir b
make O=b/nyan_big CROSS_COMPILE=arm-linux-gnueabi- nyan-big_defconfig all
You can obtain the vbutil_kernel utility here:
https://drive.google.com/open?id=0B7WYZbZ9zd-3dHlVVXo4VXE2T0U
Snow (Samsung ARM Chromebook)
-----------------------------
See here:

Nyan-big
--------
Compiled based on information here:
https://lists.denx.de/pipermail/u-boot/2015-March/209530.html
https://git.collabora.com/cgit/user/tomeu/u-boot.git/commit/?h=nyan-big
https://lists.denx.de/pipermail/u-boot/2017-May/289491.html
https://github.com/chromeos-nvidia-androidtv/gnu-linux-on-acer-chromebook-13#copy-data-to-the-sd-card
1. Patch U-Boot
Open include/configs/tegra124-common.h
Change:
#define CONFIG_SYS_TEXT_BASE 0x80110000
to:
#define CONFIG_SYS_TEXT_BASE 0x81000100
2. Build U-Boot
mkdir b
make -j8 O=b/nyan-big CROSS_COMPILE=arm-linux-gnueabi- nyan-big_defconfig all
3. Select a .its file
Select something from doc/chromium which matches your board, or create your
own.
Note that the device tree node is required, even though it is not actually
used by U-Boot. This is because the Chromebook expects to pass it to the
kernel, and crashes if it is not present.
4. Build and sign an image
./b/nyan-big/tools/mkimage -f doc/chromium/nyan-big.its u-boot-chromium.fit
echo test >dummy.txt
vbutil_kernel --arch arm --keyblock doc/chromium/devkeys/kernel.keyblock \
--signprivate doc/chromium/devkeys/kernel_data_key.vbprivk \
--version 1 --config dummy.txt --vmlinuz u-boot-chromium.fit \
--bootloader dummy.txt --pack u-boot.kpart
5. Prepare an SD card
DISK=/dev/sdc # Replace with your actual SD card device
sudo cgpt create $DISK
sudo cgpt add -b 34 -s 32768 -P 1 -S 1 -t kernel $DISK
sudo cgpt add -b 32802 -s 2000000 -t rootfs $DISK
sudo gdisk $DISK # Enter command 'w' to write a protective MBR to the disk
6. Write U-Boot to the SD card
sudo dd if=u-boot.kpart of=/dev/sdc1; sync
7. Start it up
Reboot the device in dev mode. Make sure that you have USB booting enabled. To
do this, login as root (via Ctrl-Alt-forward_arrow) and type
'enable_dev_usb_boot'. You only need to do this once.
Reboot the device with the SD card inserted. Press Clrl-U at the developer
mode screen. It should show something like the following on the display:
U-Boot 2017.07-00637-g242eb42-dirty (May 22 2017 - 06:14:21 -0600)
Model: Acer Chromebook 13 CB5-311
Board: Google/NVIDIA Nyan-big, ID: 1
Net: No ethernet found.
Hit any key to stop autoboot: 0
Tegra124 (Nyan-big) #
8. Known problems
On the serial console the word MMC is chopped at the start of the line:
C: sdhci@700b0000: 2, sdhci@700b0400: 1, sdhci@700b0600: 0
This is likely due to some problem with change-over of the serial driver
during relocation (or perhaps updating the clock setup in board_init()).
9. Notes
To check that you copied the u-boot.its file correctly, use these commands.
You should see that the data at 0x100 in u-boot-chromium.fit is the first few
bytes of U-Boot:
hd u-boot-chromium.fit |head -20
...
00000100 b8 00 00 ea 14 f0 9f e5 14 f0 9f e5 14 f0 9f e5 |................|
hd b/nyan-big/u-boot.bin |head
00000000 b8 00 00 ea 14 f0 9f e5 14 f0 9f e5 14 f0 9f e5 |................|
The 'data' property of the FIT is set up to start at offset 0x100 bytes into
the file. The change to CONFIG_SYS_TEXT_BASE is also an offset of 0x100 bytes
from the load address. If this changes, you either need to modify U-Boot to be
fully relocatable, or expect it to hang.
chromebook_jerry
----------------
The instruction are similar to those for Nyan with changes as noted below:
1. Patch U-Boot
Open include/configs/rk3288_common.h
Change:
#define CONFIG_SYS_TEXT_BASE 0x00100000
to:
#define CONFIG_SYS_TEXT_BASE 0x02000100
2. Build U-Boot
mkdir b
make -j8 O=b/chromebook_jerry CROSS_COMPILE=arm-linux-gnueabi- \
chromebook_jerry_defconfig all
3. See above
4. Build and sign an image
./b/chromebook_jerry/tools/mkimage -f doc/chromium/chromebook_jerry.its \
u-boot-chromium.fit
echo test >dummy.txt
vbutil_kernel --arch arm --keyblock doc/chromium/devkeys/kernel.keyblock \
--signprivate doc/chromium/devkeys/kernel_data_key.vbprivk \
--version 1 --config dummy.txt --vmlinuz u-boot-chromium.fit \
--bootloader dummy.txt --pack u-boot.kpart
5. See above
6. See above
7. Start it up
Reboot the device in dev mode. Make sure that you have USB booting enabled. To
do this, login as root (via Ctrl-Alt-forward_arrow) and type
'enable_dev_usb_boot'. You only need to do this once.
Reboot the device with the SD card inserted. Press Clrl-U at the developer
mode screen. It should show something like the following on the display:

flashrom
--------
Used to make a backup of your firmware, or to replace it.
See: https://www.chromium.org/chromium-os/packages/cros-flashrom
coreboot
--------
Coreboot itself is not designed to actually boot an OS. Instead, a program
called Depthcharge is used. This originally came out of U-Boot and was then
heavily hacked and modified such that is is almost unrecognisable. It does
include a very small part of the U-Boot command-line interface but is not
usable as a general-purpose boot loader.
In addition, it has a very unusual design in that it does not do device init
itself, but instead relies on coreboot. This is similar to (in U-Boot) having
a SPI driver with an empty probe() method, relying on whatever was set up
beforehand. It can be quite hard to figure out between these two code bases
what settings are actually used. When chain-loading into U-Boot we must be
careful to reinit anything that U-Boot expects. If not, some peripherals (or
the whole machine) may not work. This makes the process of chainloading more
complicated than it could be on some platforms.
Finally, it supports only a subset of the U-Boot's FIT format. In particular
it uses a fixed address to load the FIT and does not support load/exec
addresses. This means that U-Boot must be able to boot from whatever
address Depthcharge happens to use (it is the CONFIG_KERNEL_START setting
in Depthcharge). In practice this means that the data in the kernel@1 FIT node
(see above) must start at the same address as U-Boot's CONFIG_SYS_TEXT_BASE.

commit b9da5f937bd5ea4931ea17459bf79b2905d9594d
Author: Simon Glass <sjg@chromium.org>
Date: Sat Apr 15 15:39:08 2017 -0600
pci: Correct cast for sandbox
This gives a warning with some native compilers:
cmd/pci.c:152:11: warning: format ‘%llx’ expects argument of type
‘long long unsigned int’, but argument 3 has type
‘u64 {aka long unsigned int}’ [-Wformat=]
Fix it with a cast.
