From 1343bc394bb265157b2ea2d02c69cf136139a4b5 Mon Sep 17 00:00:00 2001 From: Tim Chu Date: Tue, 28 Jul 2020 04:27:35 -0700 Subject: drivers/ipmi/ocp: Add function to support OCP specific ipmi command Add driver for OCP specific ipmi commands. With this driver, OCP specific ipmi command can be used after implementing functions here. TEST=Build with CB:42242 on Delta Lake, select Kconfig option: IPMI_OCP and add device in devicetree to open this function. Use ipmi-util in OpenBMC to dump raw data and check if this function work.
