c62060d9d9 CBI: Add cbi-util
cbi-util is a build command line tool, which creates a blob containing
board information. When invoked with '--show' option, it prints the
information stored in a blob and validates the data.

BUG=b:70294260
BRANCH=none
TEST=Run the command as follows:
$ cbi-util --create /path/to/cbi.bin \
  --board_version 0xabcd --oem_id 2 --sku_id 3 --size 256
$ cbi-util --show /path/to/cbi.bin
CBI blob: /path/to/cbi.bin
  BOARD_VERSION: 0.1 (0xab.cd)
  OEM_ID: 2 (0x02)
  SKU_ID: 3 (0x03)
Data validated successfully

  --board_version 0xabcd --oem_id 2 --sku_id 3
Missing required arguments

9d38e46641 ectool: add servo v2 spi support
Add a new transport for ectool to send host command V3 over the Servo v2
SPI interface using libftdi.

Build this new communication mechanism only for the 'build' architecture
as it has a dependency on libftdi, the new ectool binary is called
ectool_servo.
Fix the 'build' tools build if they don't have a source file matching
their binary name.

The serial number of the servo board can be passed in the 'name'
parameter, e.g. :
sudo ectool_servo --name=905537-00474 version

94279fc38f Makefile: Generate hashes for the touchpad FW
Based on the passed TOUCHPAD_FW parameter to the make command, the
build system generates hashes for the touchpad FW.

To generate the hashes, gen_touchpad_hash splits the touchpad FW
in blocks of CONFIG_UPDATE_PDU_SIZE, that are hashed individually
(SHA-256), and then stored in the EC image.

This will allow the USB updater code to verify the integrity of
the touchpad firmware being flashed.

When no FW is provided, zeros are output, which do not match
any valid data.

Allow to negotiate the packet command and responses to
whatever values the EC can support.
Set the buffer size including the necessary V3 header.

If the EC run v3 protocol with large packet support, but the kernel
does not have v3 support (3.10), we can not support sending or
receiving large commands.
Be aware that on 3.10, commands like ectool console will fail if
the EC wants to send command larger than the kernel can handle.

Copied kernel_version_ge from libusb-1.0.19/libusb/os/linux_usbfs.c.

This adds a new host commmand for sending RW updates to PD devices.
The host command has a variety of sub-commands for performing the
update, including: erase RW, reboot, write new hash, write flash.

To program zinger RW, you should send host commands in this order:
write new hash to all 0's
reboot (zinger boots into RO since RW hash doesn't match)
erase RW
write flash
write new hash to match contents of RW
reboot

This also adds an ectool command to write a new RW. Just pass it
the RW .flat or .bin file.

4b59746600 util: declare all host utils source dependencies in build.mk
Instead of hardcoding the common files for host utils in the generic
rules, let's declare them in the build.mk file using the same system as
the Linux kernel build.

if a binary "foo" declared in "host-util-bin" or "build-util-bin" has a
matching "foo-objs" variable, it will be build from all objects declared
in "foo-objs" else it uses directly "foo.o" (single source file).

This is preparatory to add new "build" tools sharing common sources.

note: the dependencies on the utils are a bit less fine-grained as a
result of this change, but given the low number of tools, that should be
acceptable.

267dbb74d2 Add common interface to EC flash commands
ectool and burn_my_ec need to use the same lower-level interface to
the EC flash commands, rather than duplicating calling the low-level
flash read/write/erase commands.

This is a precursor to refactoring the low-level commands to support
SPI/STM32L in a follow-up CL.

4769627290 ectool: Add keyscan test features
Add a way of easily setting up keyscan tests using a simple text file
format. The steps to run a test are as follows:

- read the test file
- read the key matrix information
- translate the ascii characters from tests into keyscan codes
- send the keyscan codes to the EC
- tell the EC to start the test
- wait for the required time, then collect what input we have received
- check that the input matches the expected input

fbfd828b9a simple and self-contained EC flashing tool
This produces a host binary running on the application processor and
which is able to re-flash th EC firmware over the AP-to-EC link (either
LPC or I2C).
The payload (ie the EC firmware) to use is embedded inside the flasher
binary.

This is just aimed at testing and developer upgrade. The auto-update
flow is using flashrom.

8101b71316 Enable verified boot for EC firmware
BUG=chrome-os-partner:7459
TEST=manual

In the chroot:

  cd src/platform/ec
  make BOARD=link

The firmware image (build/link/ec.bin) is signed with dev-keys. Reflash the
EC and try it, and it should verify and reboot into RW A.

Additional tests (setting USE_RO_NORMAL, poking random values into VBLOCK_A
or FW_MAIN_A to force RW B to run, etc.) are left as an exercise for the
reader. I've done them and they work, though.
