| 10 | various Chromebooks and Chromeboxes. This option alone does | |
| 11 | not add any kernel code. | |

| 31 | This module instantiates the persistent storage on x86 ChromeOS | |
| 32 | devices. It can be used to store away console logs and crash | |
| 33 | information across reboots. | |

| 60 | If you say Y here, you get support for talking to the ChromeOS | |

| 70 | If you say Y here, you get support for talking to the ChromeOS EC | |
| 71 | through a SPI bus, using a byte-level protocol. Since the EC's | |
| 72 | response time cannot be guaranteed, we support ignoring | |
| 73 | 'pre-amble' bytes before the response actually starts. | |
