5*4882a593SmuzhiyunThis document describes the "marvell,berlin-smp" method for enabling secondary
6*4882a593SmuzhiyunCPUs. To apply to all CPUs, a single "marvell,berlin-smp" enable method should
7*4882a593Smuzhiyunbe defined in the "cpus" node.
8*4882a593Smuzhiyun
9*4882a593SmuzhiyunEnable method name:	"marvell,berlin-smp"
10*4882a593SmuzhiyunCompatible machines:	"marvell,berlin2" and "marvell,berlin2q"
11*4882a593SmuzhiyunCompatible CPUs:	"marvell,pj4b" and "arm,cortex-a9"
12*4882a593SmuzhiyunRelated properties:	(none)
13*4882a593Smuzhiyun
14*4882a593SmuzhiyunNote:
15*4882a593SmuzhiyunThis enable method needs valid nodes compatible with "arm,cortex-a9-scu" and
16*4882a593Smuzhiyun"marvell,berlin-cpu-ctrl"[1].

18*4882a593SmuzhiyunExample:

30*4882a593Smuzhiyun		};
