| 31 | This module instantiates the persistent storage on x86 ChromeOS | |

53 | help |
| 54 | If you say Y here, you get support for talking to the ChromeOS EC | |
| 55 | over an LPC bus. This uses a simple byte-level protocol with a | |
| 56 | checksum. This is used for userspace access only. The kernel | |
| 57 | typically has its own communication methods. | |
