arm: mediatek: dts: activate SMP for mt6589
This simple patch activates SMP for mt6589 by adding the missing
"enable-method" property. After applying this patch kernel log
indicates all cores are brought up:
[ 0.070122] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[ 0.071652] Setting up static identity map for 0x80100000 - 0x80100054
[ 0.072711] rcu: Hierarchical SRCU implementation.
[ 0.073853] smp: Bringing up secondary CPUs ...
[ 0.133675] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001
[ 0.193675] CPU2: thread -1, cpu 2, socket 0, mpidr 80000002
[ 0.253675] CPU3: thread -1, cpu 3, socket 0, mpidr 80000003
[ 0.253818] smp: Brought up 1 node, 4 CPUs
[ 0.256930] SMP: Total of 4 processors activated (7982.28 BogoMIPS).
[ 0.257855] CPU: All CPU(s) started in SVC mode.
Before this change CPU cores 1-3 didn't start and the following lines
were in kernel log:
[ 0.070126] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[ 0.071640] Setting up static identity map for 0x80100000 - 0x80100054
[ 0.072706] rcu: Hierarchical SRCU implementation.
[ 0.073850] smp: Bringing up secondary CPUs ...
[ 0.076052] smp: Brought up 1 node, 1 CPU
[ 0.076678] SMP: Total of 1 processors activated (2000.48 BogoMIPS).
[ 0.077603] CPU: All CPU(s) started in SVC mode.
