Subject: [PATCH v3 0/6] firmware: arm_scmi: imx: Dump syslog and
 system_info

System Manager firmware provides API to dump board, silicon, firmware
information. It also provides API to dump system sleep, wakeup
information. So add the interface for Linux to retrieve the information:

patch 1 is to add doc for board information which was missed before.
