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)
