The problem of sending boot logs to the booted OS has not been solved, but it is high time we do it. This proposed patch aims to give a crude solution, utilizing CONFIG_CONSOLE_RECORD to capture the logs and saving them to RAM, along with a struct residing at CONFIG_CONSOLE_RECORD_SAVE_BASE. There may be more sophisticated methods than this, which may be implemented if time permits.
Please note that this patch is not the final solution, but we do intend to finish it by the end of the MW. Also I am WFH for the holidays, so if someone could smoke-test, I'd appreciate it.
The patch series was based on the current tip of `next` branch: Commit: 4b151562bb bootmeth: pass size to efi_binary_run()
