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.

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.
