Subject: [PATCH 1/3] ARM: dts: rainier: Add reserved memory for ramoops
Date: Fri,  2 Oct 2020 16:04:12 +0930
Message-ID: <20201002063414.275161-2-andrew@aj.id.au> (raw)
In-Reply-To: <20201002063414.275161-1-andrew@aj.id.au>

Reserve a 1MiB region of memory to record kmsg dumps and console state
into 16kiB ring-buffer slots. The sizing allows for up to 32 dumps to be
captured and read out.
