Subject: [PATCH v2 0/2] ARM: oxnas: Add SMP support for OX820
Date: Fri, 21 Oct 2016 10:58:46 +0200 [thread overview]
Message-ID: <20161021085848.1754-1-narmstrong@baylibre.com> (raw)
In order to support the SMP feature of the Oxford Semiconductor OX820 SoC,
add the necessary code to handle the wake-up, hotplug and cpu entry.
The OX820 has an ARM11MPCORE cluster with 2 cores and has proper hardware
support for secondary core booting.
Changes since v1 at http://lkml.kernel.org/r/20161017084303.20078-1-narmstrong at baylibre.com
- Remove useless holding pen loops and spinlock in boot_secondary
