Help¶

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)
