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

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

  53           If you say Y here, you get support for talking to the ChromeOS EC
  54           over an LPC bus. This uses a simple byte-level protocol with a
  55           checksum. This is used for userspace access only. The kernel
  56           typically has its own communication methods.
  57
  58           To compile this driver as a module, choose M here: the
  59           module will be called cros_ec_lpc.
