   9           Say Y here to get to see options for platform support for
  10           various Chromebooks and Chromeboxes. This option alone does
  11           not add any kernel code.

  22           light sensors and touchpads.

  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.

  35           The range of memory used is 0xf00000-0x1000000, traditionally
  36           the memory used to back VGA controller memory.

  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.
  58
  59           To compile this driver as a module, choose M here: the
  60           module will be called cros_ec_lpc.
