communication with the host processor.

Hi Joel & Andrew,

The kcs-bmc-aspeed module has been in:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/char/ipmi/kcs_bmc_aspeed.c
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/ipmi/aspeed-kcs-bmc.txt

I updated the device tree node about kcs-bmc, this is passed on my board.

And the patch is generated by rebasing on:
https://git.kernel.org/pub/scm/linux/kernel/git/joel/aspeed.git
Please help to review.

BR,
Haiyue
