Subject: [PATCH v2 0/6] firmware: arm_scmi: imx: Dump syslog and
 system_info

Cristian,
  I only kept your R-b for patch 1, dropped your other R-b tags, because
  there are some changes to address the comments from Sudeep. Most changes
  are only to dump the information in probe phase, update to single sysfs
  single value for syslog.

Sudeep,
  I saw you sent out PR to Arnd for 6.17, so no rush now for this patchset.
  Take your time.

Hope I not miss any comments from V1.

Thanks,
Peng

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.

Changes in v2:
- Add more info in patch 1 for documentation(attribute is reserved for
  future use, boardname may not align with the board name in device tree)
- Drop dump silicon revision API
- Update discover build info, cfg info, board info API to be only used in probe phase
- Update to use single sysfs single value for syslog.
- Link to v1: https://lore.kernel.org/r/20250627-sm-misc-api-v1-v1-0-2b99481fe825@nxp.com
