How to use eSPI between Host and slave BMC in openbmc project

[Wang, Kuiying]

Hi  Felix,

Both KCS and eSPI driver are ready x86 platforms.
Please refer https://github.com/Intel-BMC/

Example:
https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-ast2500/recipes-bsp/u-boot/files/0022-KCS-driver-support-in-uBoot.patch
https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-ast2600/recipes-bsp/u-boot/files/0005-Ast2600-Enable-interrupt-in-u-boot.patch
https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-common/recipes-kernel/linux/linux-aspeed/0022-Add-AST2500-eSPI-driver.patch


BTW: you could set Acute travel logic to analyze eSPI bus. There is eSPI connector on Intel CRB platform.

Thanks,
Kwin.




Dear James/andrew/Oskar

    Thanks a lot.

    I am studying eSPI spec. But it's hard to find any products with eSPI.

    Your reply gives more understanding about eSPI.



    Looking forward to more applications with eSPI in openbmc project.

    Thanks again.

BR

Felix
