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

12 If you say N, all options in this submenu will be skipped and disabled.

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.

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

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.
