From 3acea5c51abd09bb578cfb35952b9dbd96be21fe Mon Sep 17 00:00:00 2001 From: Johnny Lin Date: Fri, 8 Jan 2021 15:24:25 +0800 Subject: ipmi/ocp: Move common OCP/Facebook IPMI OEM codes into drivers/ipmi/ocp 1. These are common OCP/Facebook IPMI OEM commands, move from mainboard into drivers/ipmi/ocp to avoid code duplication and provide better reusability. 2. OCP Tioga Pass enables IPMI_OCP driver. Tested=On OCP Delta Lake and Tioga Pass verify the commands still work correctly.
