Subject: [PATCH 0/5] ARM: SMP: support Broadcom mobile SoCs
Date: Thu,  3 Apr 2014 21:18:06 -0500	[thread overview]
Message-ID: <1396577891-2713-1-git-send-email-elder@linaro.org> (raw)

This series adds SMP support for two Broadcom mobile SoC families.
It uses CPU_METHOD_OF_DECLARE() (or rather a new variant of that)
so that SMP operations are assigned using device tree rather than
adding it to a machine definition in a board file.

The first patch adds the ability to extract information from device
tree nodes having a matching "enable-method" value.  This allows
additional parameters to be associated with the enable method.  This
is used for the Broadcom SoCs to efficiently determine the location
of a special register used in coordinating the start of secondary
CPUs.

I have not included a device tree document update here; I would like
suggestions on where the new enable method and its parameter should
be documented.  (I presume in .../arm/cpus.txt, but that could get
out of hand as more boards define new enable methods.)
