From df503ba7f653c590b475ab80bde788edf5af70d5 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 14 Nov 2013 15:15:37 +0000 Subject: [PATCH] arm64: dts: Reserve the memory used for secondary CPU release address With the spin-table SMP booting method, secondary CPUs poll a location passed in the DT. The foundation-v8.dts file doesn't have this memory reserved and there is a risk of Linux using it before secondary CPUs are started.
