The ChromeOS EC is connected by LPC only on x86 platforms and no others, so add a dependency describing that. But also build the driver if the COMPILE_TEST option is enabled to have build coverage in other architectures.

various Chromebooks and Chromeboxes. This option alone does

not add any kernel code.

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 have a supported Chromebook, choose Y or M here.

help
|
|
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.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called cros_ec_lpc.
