[PATCH 0/7] arm64: Initial SoC support (ARMv8 RTSM model)

[Catalin Marinas]

Hi,

This series adds support for the ARMv8 RTSM model. It is based on
linux-next (it requires Pawel's patches for vexpress) and does not yet
use GIC (waiting for the GICv2 move from arch/arm to drivers/irqchip to
complete).

The aim is to have minimal or no SoC support at all. On vexpress, because the
clocks must be initialised before populating the AMBA devices, I added an
arch_initcall(). Platforms that rely solely on device driver probing don't
need any platform code.

Still to be done is Documentation/arm64/soc.txt with requirements for SoC
support on AArch64.

Comments welcome. Thanks.
