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 https://www.intel.com/content/www/us/en/support/articles/000020952/ software/chipset-software.html for more detail.
