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. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> 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.
