[RFC PATCH 0/5] arm64: prepare for basic Allwinner support

[Andre Przywara]

This is a first step for introducing support for the Allwinner A64
SoC that made a recent appearance on the Pine A64 board featured on
Kickstarter.
This mini-series prepares the ground by allowing ARCH_SUNXI to be
defined for an arm64 kernel.
The patches fix some minor warnings which appear when Allwinner
(aka. sunxi) drivers are compiled for a 64-bit architecture.

Due to a lack of official documentation and hardware availability
this doesn't go any further at this moment.

Please have a look and comment!

Cheers,
Andre.

Andre Przywara (5):
drivers: sunxi-rsb: fix error output type
crypto: sunxi-ss: fix min3() call to match types
crypto: sunxi-ss: fix dev_dbg() output type
irqchip: sun4i: fix compilation outside of arch/arm
arm64: Introduce Allwinner SoC config option

The length parameter in this dev_dbg() call is actually a size_t,
so use the proper type to avoid warnings when compiling for 64-bit
architectures.

"len" is actually a size_t in this function here, so properly annotate
the dev_err printf type to allow compilation for 64-bit architectures.
