Documentation: power: Add document on debugging shutdown hangs If the kernel hangs while shutting down, ideally a UART log should be captured to debug the problem. However if one isn't available, users can use the pstore functionality to retrieve logs. Add a document explaining how this works to make it more accessible to users. Tested-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Mario Limonciello (AMD) <superm1@kernel.org> Link: https://patch.msgid.link/20251025004341.2386868-1-superm1@kernel.org Signed-off-by: Rafael J.

Documentation: power: Correct a mistaken configuration option Somehow CONFIG_PSTORE_FIRMWARE ended up in this document when I intended it to be CONFIG_CHROMEOS_PSTORE. Correct the configuration option and make it clear that not all options are required.
