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.

BUG=None
TEST=build for link/daisy/snow/bds and tests
On Snow, run burn_my_ec from the serial console and see that the EC was
correctly re-flashed.

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.

c74bd90fb0 stm32l: add a tool to flash the SoC using the serial monitor
When run with BOOT0=1 and BOOT1=0, the STM32L enters a system monitor
which allows flashing over the serial port (USART1 pins PA9 and PA10).
Implement commands to flash and run a program from a linux Host.

TEST=on a serial port connected to Discovery board pins PA9 and PA10,
run manually the various tools commands.

bc4c1b4eb9 Separate utility build for build and host utils
Build is the system doing the build (e.g. 64-bit linux) and host is the
target platform on top of the ec (e.g. 32-bit Chromium OS).

Necessary to get ectool properly compiling for Chromium OS.
