Subject: [PATCH 0/4] ARM: sunxi: Clean and improvements for multi-cluster SMP

Hi,

This series is a bit of cleanup and improvement for the new
multi-cluster SMP code for Allwinner A80 and A83T (soon) SoCs.

The first patch is just a typo fix.

The second and third patch add the use of the "enable-method" cpu
property to enable SMP, instead of matching against the machine
compatible. However, due to how init calls are sequenced, we still
need to use a platform early_init call.

The last patch splits out parts of the SoC-specific init code, i.e.
the device node matching parts. This should help with Mylene's work
on adding support for the A83T.

Please have a look.

Regards
ChenYu
