*eSPI emulator*

Type: ``bool``

Help

.. code-block:: none

    Enable the eSPI emulator driver. This is a fake driver,
    it does not talk to real hardware. Instead it talks to emulation
    drivers that pretend to be devices on the emulated eSPI bus. It is
    used for testing drivers for eSPI devices.

    eSPI is an interface using SPI wires, whose main goal is to reduce the
    number of required pins. It includes the functionality of LPC, SMB, SPI
    itself (flash access) and GPIO (virtual wires). Please refer to the
    specification for more details (it is good for the introduction as well)
