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.
The module will be called chromeos_pstore.
