From c1fc133f5bd06949037192c0a48c3dab85a140fd Mon Sep 17 00:00:00 2001 From: Andrew Jeffery Date: Thu, 22 Oct 2020 12:17:31 +1030 Subject: ARM: dts: tacoma: Add reserved memory for ramoops Reserve a 1.5MiB region of memory to record kmsg dumps, console and userspace message state into 16kiB ring-buffer slots. The sizing allows for up to 16 dumps to be captured and read out. Set max-reason to KMSG_DUMP_EMERG to capture bad-path reboots.
