| 5 | Enable command-line access to the Chrome OS EC (Embedded |
| 6 | Controller). This provides the 'crosec' command which has |
| 7 | a number of sub-commands for performing EC tasks such as |
| 8 | updating its flash, accessing a small saved context area |
| 9 | and talking to the I2C bus behind the EC (if there is one). |

| 14 | Enable access to the Chrome OS EC. This is a separate |
| 15 | microcontroller typically available on a SPI bus on Chromebooks. It |
| 16 | provides access to the keyboard, some internal storage and may |
| 17 | control access to the battery and main PMIC depending on the |
| 18 | device. You can use the 'crosec' command to access it. |

| 24 | Enable I2C access to the Chrome OS EC. This is used on older |
| 25 | ARM Chromebooks such as snow and spring before the standard bus |
| 26 | changed to SPI. The EC will accept commands across the I2C using |
| 27 | a special message protocol, and provide responses. |

| 32 | help |
| 33 | Enable I2C access to the Chrome OS EC. This is used on x86 |
| 34 | Chromebooks such as link and falco. The keyboard is provided |
| 35 | through a legacy port interface, so on x86 machines the main |
| 36 | function of the EC is power and thermal management. |

| 42 | Enable a sandbox emulation of the Chrome OS EC. This supports |
| 43 | keyboard (use the -l flag to enable the LCD), verified boot context, |
| 44 | EC flash read/write/erase support and a few other things. It is |
| 45 | enough to perform a Chrome OS verified boot on sandbox. |

| 52 | ARM Chromebooks such as pit, pi and nyan-big. The SPI interface |
| 53 | provides a faster and more robust interface than I2C but the bugs |
| 54 | are less interesting. |
