cros_ec: Implement I2C pass-through

2014-03-18T02:05:48+00:00

The Chrome EC has a feature where you can access its I2C buses through a
pass-through arrangement. Add a command to support this, and export the
function for it also.

cros_ec: Clean up multiple EC protocol support

2014-03-18T02:05:47+00:00

Version 1 protocols (without command version) were already no longer
supported in cros_ec.c.  This removes some dead code from the
cros_ec_i2c driver.

Version 2 protcols (with command version) are now called
protocol_version=2, instead of cmd_version_is_supported=1.

A subsequent change will introduce protocol version 3 for SPI.

cros_ec: Add a function for decoding the Chrome OS EC flashmap

2014-03-18T02:05:46+00:00

In order to talk to the EC properly we need to be able to understand the
layout of its internal flash memory. This permits emulation of the EC
for sandbox, and also software update in a system with a real EC.
