drivers/ipmi/ocp: Add ipmi set processor information
Implement setting processor information to BMC based on document YosemiteV3_BMC_Feature_Spec_v1.7. TEST=Use get command in OpenBMC to check. Command and information are shown as below: root@bmc-oob:~# ipmi-util 1 0xd8 0x11 0x4c 0x1c 0x00 0 1 DC 11 00 47 65 6E 75 69 6E 65 20 49 6E 74 65 6C 28 52 29 20 43 50 55 20 30 30 30 30 25 40 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 root@bmc-oob:~# ipmi-util 1 0xd8 0x11 0x4c 0x1c 0x00 0 2 DC 11 00 1A 34 00 DC 05 41 30 root@bmc-oob:~# Signed-off-by: Tim Chu <Tim.Chu@quantatw.com> Change-Id: I3d53ac241a11ca962572816283a0c653fcde9f9e Reviewed-on: https://review.coreboot.org/c/coreboot/+/42242 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
