CONFIG_ESPI_NPCX
Nuvoton NPCX embedded controller (EC) ESPI driver
Type: bool
Help
Enable support for NPCX ESPI driver. The Intel Enhanced Serial
Peripheral Interface (eSPI) provides a path for migrating host
sub-devices via LPC to a lower pin count, higher bandwidth bus.
So far, this driver supports all of functionalities beside flash
channel support. It will be supported in the future. Please refer
