| This module instantiates the persistent storage on x86 ChromeOS | |
| devices. It can be used to store away console logs and crash | |
| information across reboots. | |
| The range of memory used is 0xf00000-0x1000000, traditionally | |
| the memory used to back VGA controller memory. | |

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

| If you say Y here, a variant LPC protocol for the Microchip EC | |
| will be used. Note that this variant is not backward compatible | |
