Subject: [PATCH v6 0/4] ARM: SMP: support Broadcom mobile SoCs
Date: Mon, 30 Jun 2014 17:15:36 -0500 [thread overview]
Message-ID: <1404166540-4457-1-git-send-email-elder@linaro.org> (raw)
This series adds SMP support for two Broadcom mobile SoC families.
It uses CPU_METHOD_OF_DECLARE() so that SMP operations are assigned
using device tree rather than adding it to a machine definition in a
board file.
The enable method starts a secondary core by writing to a register
monitored by CPUs spinning in a ROM-based holding pen loop. The
address of this register is recorded as a property in the "cpus"
node of the device tree.

Notes:
- This series previously included the binding as its first patch. That
has now been posted separately to facilitate and focus review.
- This series is based on v3.16-rc1, plus two recently-posted patches:
