Subject: [Qemu-devel] [PATCH 2/2] arm: highbank: setup custom MPIDR value
Date: Mon, 24 Feb 2014 16:14:46 -0600	[thread overview]
Message-ID: <1393280086-19431-2-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1393280086-19431-1-git-send-email-robherring2@gmail.com>

From: Rob Herring <rob.herring@linaro.org>

Calxeda highbank platform uses a cluster id of 9 which makes MPIDR
register be 0x8000090n where n is the core number. This causes problems
on current kernels expecting the MPIDR to match DT cpu reg property.

Midway is "normal" and has a cluster id of 0, so it does not need this
override.
