Subject: [PATCH] arm64: dts: msm8994-angler: fix the memory map
Date: Fri, 30 Dec 2022 20:48:45 +0100	[thread overview]
Message-ID: <20221230194845.57780-1-dominikkobinski314@gmail.com> (raw)

Add reserved regions for memory hole and tz app mem to prevent
rebooting. Also enable cont_splash_mem, it is the same as the
generic 8994 one.
